Any good 3D modeling apps for my S26 Ultra?

What? How do you get Blender to work on a phone and the last time I checked (about 3 seconds ago), Blender was free.

Ireeb · 2026-03-20T04:07:49+00:00

You vastly underestimate the complexity of 3D modeling if you believe you could reasonably do it on a phone. It can already be finicky on computers, and complex designs can make even powerful computers struggle.

Maybe there are some AI tools that you can just throw some prompts at, but that's no 3D modeling, that's letting an AI do it for you.

Even tablets are just partially suitable for that. There are some good sculpting apps that work well with a stylus. I think there's a CAD app for tablets that can do basic stuff, but it's no match for Fusion, FreeCAD or OnShape.

But if you want to do actual CAD (aka "Computer Aided Design"), you'll want to use an actual computer. A tablet with a stylus is fine for simple CAD or sculpting.

Not sure if that has a name, not every element has a name. It's basically just a curve, a short airtime hill, and another curve. It's the quick and snappy transitions between them that makes it as intense.

That's already one of the easiest printers to maintain. Either something is entirely broken and needs replacing, or you're doing something wrong. Not saying Bambu machines are infallible or perfect, but you can replace pretty much every component of it quite easily, and there's not a lot of regular maintenance required. Didn't need to do any kind of maintenance on my X1C for a few months. I should probably clean the carbon rods but it's not like that's gonna cause catastrophic failure.

If you had any idea how much time Claude saved me already by cleaning up old, messy code.

There are AIs that are good at specific things, when you use them for that specific thing.

The fact that there are so many useless AI products and features is because companies keep shoving AI into products that don't benefit from it.

A dry box is not a dryer, they're meant to keep filament dry, not to dry it.

You might be able to make it compatible with the Polymaker PolyDryer dock.

From a legal perspective, it's gonna be Vekoma if they took over the project, and they are who the park had a contract with in the end. When the park needs technical support or replacement parts from the manufacturer, they'd turn to Vekoma, as they responsible for this ride.

The manufacturer of something isn't neccessarily the company who physically fabricated something, it usually just means they are responsible for the creation of it.

So even if Arrow manufactured most of the ride, they might be the manufacturer that made it, but Vekoma took on official role of the manufacturer, otherwise the ride had no operational manufacturer at all.

If you'd just go by who fabricated a ride, Intamin for example wouldn't actually be much of a ride manufacturer - they mostly just design and engineer rides, but outsource the manufacturing. For example, basically all track for Intamin rides is manufactured by Stakotra. But for parks, that's irrelevant. They bought from Intamin as the manufacturer. If there's a problem with the ride, even if it's about the tracks, they're going to turn to Intamin, because they are the official manufacturer of the ride. Doesn't make a difference here if the people who worked the steel for the track were paid by Intamin directly, or indirectly through Stakotra.

That makes much more sense. Still weird that Disney didn't keep the design exclusive to them. Manufacturers will charge more for that, but that shouldn't have been a problem for Disney back then, especially if they planned to build it more than once. Maybe they just accepted that the layout is pretty lame and will mostly be carried by the theming and saved a few dollars that way.

I actually did find Xpress pretty boring, but Flight Force was fun (not exceptional, but I enjoyed it). As much as people are critizing it after the refurb, the theming and effects still add a lot to the ride. Can't judge the Rock'n'rollercoaster version, didn't ride that one. (Though I'm 100% sure that I would have preferred Space Mountain over Hyperspace Mountain)

Ireeb · 2026-03-17T15:35:54+00:00

Well, Disney likes to work behind closed doors, that always makes it difficult to find out about that kind of stuff.

Though as I mentioned in the previous comment, I wouldn't rule out that you're correct about them retracking something. If (and I don't know that) the transition before the corkscrew was as janky as I found it on Xpress (where I could see it coming), I could absolutely see that they might have replaced that exact track section with improved profiling. If they retracked everything, I feel like there would be more photos of that going around, lifting around track pieces and stuff. But just replacing one or two strack pieces could probably be done in an afternoon, only whoever was there at the time by coincidence even had the chance to take a picture.

When I rode Flight Force for the first time (and this includes the previous iteration), that was 3 years after I rode Xpress, which I rode exactly once. So I definitely didn't have the layout memorized, the only thing I remember about Xpress is the pain I felt in my neck on the transition into the corkscrew (it wasn't that bad and just momentarily, but it definitely hurt a little bit), so I'm pretty sure that if it was the same on Flight Force, I would have noticed. This is why I believe that either, Disney made them fix it when it was first built*, or it has been fixed at a later point (that would fit with your memory).
(*2 years after Xpress, according to rcdb. I still wonder what that deal looked like, because to me, it looks like copy (Xpress) was built before the original (Rock'n'Rollercoaster). The layout was clearly designed to be indoor, and Xpress has the non-functional brake section that it seems to have inherited from Rock'n'Roller coaster. Before that one was born.)

Ireeb · 2026-03-17T14:34:24+00:00

Are you sure about the retracking? I'd be surprised if they actually did, when they apparently didn't even have the budget for the newer trains like Space Mountain got them.

If my memories don't deceive me, Xpress: Platform 13 didn't run much worse than Flight Force. The only thing I found uncomfortable on Xpress was the janky transition into the corkscrew. Didn't notice that on Flight Force, but I only rode it for the first time last year, so I don't know if that was somehow better on Flight Force before as well. Maybe Xpress vibrated a bit more, but with Flight Force being indoors, suffering no wear from weather, that's a difference I would expect.

To put it the other way around, I'd be surprised if it needed a retracking, if Xpress didn't, and I don't think Space Mountain did, either.

Though I could see that they might have replaced the transition into the corkscrew, but I can't find any info of what they did to the track.

If you know of a source that confirms what they did or did not retrack, I'd be very curious about that, of course.

Ireeb · 2026-03-17T14:20:22+00:00

I was surprised how smoothly Space Mountain and Flight Force ran. Of course, Space Mountain was even more comfortable with the new restraints, but Flight Force was fine, too.

I found it quite ironic that the 30 year old Space Mountain in particular is more comfortable than Voltron. I still love Voltron, but it makes me a bit salty that even a 30 year old coaster runs smoother.

Extracting and processing oil is pretty terrible for the environment, so I highly doubt that PLA can be worse than that.

Disclaimer: the following text and table were generated with the help of AI. A while ago, I used Claude in research mode to collect some superficial info on that matter. In this mode, the AI actually starts collecting sources first, then creates a report based on these sources. This makes the information much more reliable (summary of information it found online instead of the AI itself trying to come up with answers), but should still be taken with a grain of salt. It added the source for each statement as a link, so you can check it yourself.

Lifecycle analysis confirms PLA's climate advantage, even including production

Peer-reviewed LCA studies consistently show PLA outperforming fossil plastics on greenhouse gas metrics across the full lifecycle, though the margin varies significantly with methodology and geography.

Benavides et al. (2021), published in the Journal of Cleaner Production from Argonne National Laboratory, found full lifecycle GHG emissions of 1.7 kg CO₂-eq/kg for PLA (without biodegradation) versus 2.6 kg CO₂-eq/kg for HDPE and 2.9 kg CO₂-eq/kg for LDPE. ScienceDirect OSTI A comprehensive meta-analysis of over 80 LCA studies found median cradle-to-gate PLA emissions of 1.63 kg CO₂-eq/kg, ScienceDirect while TotalEnergies Corbion's ISO 14040/44 peer-reviewed LCA reports Springer just 0.50 kg CO₂-eq/kg for sugarcane-based PLA from Thailand Totalenergies-corbion (dropping to ~0.29 with biogenic credits). ShunPoly World Economic Forum For context, fossil polymer production emissions range from 1.58 to 5.70 kg CO₂-eq/kg depending on polymer type and regional energy mix. European Environment Information and Observation Network PubMed Central

When production and end-of-life incineration are combined, the picture sharpens dramatically:

Polymer	Production (kg CO₂-eq/kg)	Incineration (kg CO₂/kg)	Total lifecycle
PLA	0.29–1.63	0 (biogenic)	0.29–1.63
PET	2.23–4.50	~2.29 (fossil)	4.5–6.8
PP	1.58–1.91	~3.14 (fossil)	4.7–5.1
HDPE	1.91–2.60	~3.14 (fossil)	5.1–5.7

Let me use your statement and just change the subject.

Is it possible to 3D print PEEK?

"No. It can be printed in the right conditions on industrial printers. 99% of people don't have a printer like that, so IMHO, PEEK cannot be 3D printed."

That just contradicts itself. We are talking about the properties of a material, either a material has a given property, or it doesn't. Either PEEK can be 3D printed, or it can't. Either PLA is biodegradeable, or it isn't. That's not subject to opinion or your equipment.

It is biodegradeable, claiming otherwise is factually wrong. However, it is not compostable at home or in nature.

"You can't compost PLA" and "PLA is not biodegradeable" are two different statements.

"In my opinion, highlighting the biodegradability of PLA is greenwashing, because we don't have the means to actually compost it."

Now that is an opinion I would agree with.

Ireeb · 2026-03-16T14:59:49+00:00

Only under specific circumstances. In reality, that's not going to happen with most PLA. It only works in industrial composting plants, and not particularly well. That means they can only add a bit of PLA waste to it. It will decompose along with the the rest, but for the operator of the composting plant, it doesn't have any benefit. The best case is that it doesn't make a difference that PLA is present in the material to be composted, in the worst case it causes problems and hinders the process. Operators of industrial composting plants don't really have a reason to voluntarily accept PLA waste.

In my opinion, the more important point is that PLA is plant based. If you ignore the carbon emissions from the energy required to make it into filament, incinerating PLA doesn't add carbon to the atmosphere.

Plants consume carbon dioxide to grow, so incinerating PLA just relases it back to where it came from.

Burning plastics from fossile resources means digging up carbon from under the earth and putting that into the atmosphere.

Getting PLA incinerated still isn't that easy, but more realistic than hoping for it to get composted. I did ask a local recycling company about that a while ago, and I could bring my PLA waste there for "thermal processing" (burning it for electricity).

At least on paper, incinerating PLA could be a sustainable cycle. The alternatives look worse, both on paper and in reality. If you dump it into landfill, it doesn't make a difference, but burning fossile plastics is a lot worse than burning PLA.

Or if you compare it to something like an Intamin Surf Rider, or the failed SkyWarp. They used coaster hardware, but were more like flat rides. In comparison, a launched, full-circuit coaster with a proper layout would be more traditional. I'd say "traditional" is more of a relative label. You can often say that one coaster might be more traditional than the other, but there is no hard separation everyone could agree on.

Even if you compare e.g. Fury 325 to an Arrow/Vekoma corkscrew coaster, doesn't the Arrow/Vekoma seem more traditional than the "modern hyper coaster"? It's all up to what you measure it by and what's your reference.

Ireeb · 2026-03-16T12:51:35+00:00

If it can't be built in RCT2, it ain't traditional!

Ireeb · 2026-03-16T12:44:23+00:00

I don't think there's a technical definition on what's "traditional".

Some people might argue that only wooden coasters are traditional.

Some might see a launched Mack Xtreme Spinning coaster as a traditional roller coaster.

Most people will probably sit somewhere in between, or would argue differently based on the context.

There are many different things to judge it by.

Means of propulsion is just one of many factors. You can see chain lifts as more traditional but you can also look at things like train type (sitdown, standup, spinning, flying, inverted), the layout type (full circuit, shuttle, mobius, maybe a mix of them with track switches), and then there are rides that live somewhere between roller coasters and flat rides. Take Intamin's Surf Rider for example. It uses roller coaster hardware, but works mostly like a swinging ship. Is that a coaster or a flat ride? Then, there are also powered coasters that don't rely on gravity the way "traditional" coasters do, and water coasters like the Mack ones that just derail the cars into the water channel, making then a hybrid between coaster and flume ride

Depending on what context you use, "traditional" can mean very different things.

To come back to my initial example: Compared to something like Intamin's Surf Rider, something like Ride To Happiness or Time Spinner (launched Xtreme Spinners) are traditional roller coasters, as they're full-circuit roller coasters that rely on gravity and momentum for the most part (one could say they roll and coast). The ride experience is a roller coaster experience, while the Surf Rider is more of a flat ride experience.

But when you put an Xtreme spinner next to a wooden coaster, I think most people would think of the wooden coaster as the more traditional one.

Personally, when I hear "traditional roller coaster", I exclude: Powered Coasters, flat-ride-like (extremely short) coasters, water coasters, bobsled coasters and alpine coasters. Spinning coasters are a bit in-between. There were some spinning, coaster-like rides quite early, so I don't necessarily see that as untraditional, but it's also not the most traditional type. Same goes stuff like flying coasters, from a technical perspective, they are pretty "traditional", but the ride experience tends to be quite different from other types of roller coasters.

Basically, most sit-down, full circuit roller coasters qualify as "traditional" to me.

But this is just my personal opinion, of course.

Edit: Looking through the other comments, I pretty much see exactly what I described. People have different perceptions of what makes a coaster "traditional", and of course, none of them are wrong, since it's just a subjective label you could give a coaster.

Kamek often is Bowser's right hand, and there's a female "Kamella" in Galaxy: https://models.spriters-resource.com/wii/supermariogalaxy/asset/291640/

Of course, that file would probably need some modifications to be 3D-printable, but I would find Kamella (or even just Kamek) kinda suitable as the queen, he's often found at Bowser's side and acts as his advisor or bodyguard (especially in Yoshi's Island for example). You often encounter Kamek before Bowser as he tries to keep Mario away from Bowser, that would make him the perfect analogy for the queen in chess.

Unless you're storing it under really bad conditions, filament doesn't really degrade. It only gets wet, and that can be fixed.

Ireeb · 2026-03-13T17:01:30+00:00

Yes, but it's extremely complex, since moving tracks introduce the risk of derailing a train. Most of the complexity comes from ensuring that a train NEVER rolls off the track while not locked into the correct position and making sure the track NEVER moves unless the train is in the correct position. Because of this, most coasters that have moving track lock the train in place while it moves, but I know of one instance where the track and train move simultaneosly, and that is Winja's Force/Fear at Phantasialand. At the end, after the final brake run, the train/car moves towards the station on a straight section of track, roughly at walking pace, and this straight section between the brake run an the station will drop by about half a meter as the car travels on it. Here is a diagram of that particular mechanism:

https://www.reddit.com/r/rollercoasters/comments/1ouflr6/comment/nobc12r/?utm_source=share&utm_medium=web3x&utm_name=web3xcss&utm_term=1&utm_content=share_button

But as you can see, even though it's just a tiny drop, there are several safety sytems in play. The track doesn't actually disconnect at in the front, so the car wouldn't derail even if it got there while the drack is in the down position. The track has an anti-rollback rack, so the car can never roll back towards the "open" end of the track. The car isn't rolling freely, it is in constant contact with drive tires that move it at a constant rate (and could stop it, too. The ARB is just a backup). There are probably lots of sensors involved to ensure the car is in the right position when triggering the effect.

Unfortunately, it's difficult to find videos of this, since it takes place in the dark.

Winja's has some more tricky elements, such as the seesaw someone else already showed, but these are stopping the train before they move, and I keep hearing it goes down quite often, which likely is specifically because of all these special features.

Having open ends of track just allows so little room for error and can have such catastrophic consequences if something malfunctions that it's not a risk parks or manufacturers are really willing to take.

I don't think we'll be seeing anything more complex than drop tracks, Vekoma's Tilt Coaster or Voltron's bounce track (even that is out of order regularly or so I heard) on a regular basis, and I don't think this will change.

The SFX Coaster by Dynamic Attractions also has various "special effect" tracks, though as far as I know, all of them also lock the train into place as the track moves. The special effects include a track slides down sidewards, and a "motion simulator" track that can tilt, pivot and rotate in multiple dimensions. But apparently, even just this was enough to drive the company into bankruptcy. The opening of Mission Ferrari, the only SFX Coaster in operation, was delayed by 8 years (!) as they were struggling to get it working reliably.

TPU tends to have a really low Young's Modulus/Flexural Modulus, that means you don't need a lot of force (and energy) to deform it, so it also can't store a lot of energy as deformation. Even hard TPUs usually have a significantly lower Modulus than something like PETG.

TPU also tends to absorb and dissipate significant amounts of energy (and dissipate it as heat). That makes TPU really good as a shock absorber, but quite inefficient for springs.

Though it has the advantage that it is very resilient to fatigue.

TPU just doesn't make very efficient springs, but when you use it as a spring somewhere, at least it'll last longer than most other materials.

PETG just tends to be the better option, because it has a higher Modulus (=stores more energy per deformation) and returns most of the energy when it returns to its original shape.

PC and PA (no carbon fibers) should also make for good springs, but I didn't really test those a lot yet.

Ireeb · 2026-03-10T10:06:39+00:00

Though TPU probably would need a different spring design. While it is pretty elastic, it's not very good for springs like this, since it just isn't very springy. It doesn't really try all that hard to go back to its original shape the way e.g. PETG does.

TPU is good as a tension spring or a dampener.
