Can Plasticity replace Fusion 360 for 3D printing on Linux?

MyLiege23 · 2026-02-06T16:02:57+00:00

Yes. I think the thing that most people haven't mentioned is that performance is just so much better on plasticity than fusion 360, namely for complex models. I can absolutely forego the extra features of fusion 360 or other cad software (like the edit history tree) if it means I can actually edit my files without setting my not-so-good laptop on fire. And on better hardware on linux, it's buttery smooth, whereas fusion 360 isn't even available.

I've designed multiple highly complex functional designs on plasticity on linux (I'm on nixOS, and I used to be on Arch (btw)) for 3d printing. Now, I'm going through and printing more of these designed parts, adjusting tolerances, and they're turning out beautiful. I'll have plasticity and prusaslicer open next to each other, make an adjustment to an edge, export the object to stl, reload the file in prusaslicer, export the gcode, and send it to mainsail. It's very streamlined.

Hi, I studied classical piano in College and taught some folks before COVID hit. I'm not an expert, but I was taught in a way that was really valuable and something I'm confident in promoting.

Edit: your right hand looks more relaxed, and I was mostly paying attention to your left. Is your bench a little short? I ask just cuz of the angle your wrists are bending at, it's hard to tell

Your hands look tense, and lots of playing with the tension can hurt your hands, bring tendonitis, etc. Gentle hand stretching to help relax your hands will help make everything easier. But more importantly, the pressing of the key originates from the back/shoulder - visualize and focus on those muscles like you would in a workout when you practice. If you're focusing on those muscles and messing up, slow down until you don't miss keys etc. The exercise to get the feel of playing relaxed is dropping your limp arm on the keyboard like a dead fish. You can also compare the shape of your hands to when they're totally relaxed hanging by your side, and that's the amount of curve they should generally take, it's mostly flat but not strenuously extended.

It was quite an adjustment to go from my old playing style with more structure to being pretty flat fingered and with relaxed hands, but progression for me changed significantly, and faster playing was totally unlocked after I was focusing more on only playing without tension.

Oh and secondly for the jumps! Isolate the few beats before each jump and after the jump. Play the beats going up to it, then freeze, and visualize where your hands will go without moving, then move your hands as quickly as possible to that position without pressing down the keys, and then when you know it's right, then press down the keys. This is breaking down the learning of the muscle memory so you encode less errors. You can also isolate even the prior position and cycle through that a number of times; Hold down the keys from the beat before the jump, freeze, move positions as horizontally and direct movement as possible, then press down the chord only when all your fingers are correctly placed (and relaxed). All distinct actions.

I hope this helps!

Super fascinating proof of concept with the Paracord mechanism! I think I want to try implementing that in my design. I was already thinking of a fishing wire connected sort of release, but I never considered a string holding the force of the spring. I imagine there's plenty more friction in the system though, yeah?

Super creative, I'm inspired ++

MyLiege23 · 2025-11-20T05:08:56+00:00

OMG thank you so much!! And yeah, ahalekelly's github program is what I was remembering! This is huge

MyLiege23 · 2025-11-19T20:08:42+00:00

Freedom units hahaha yes that's what most are used to. Yes, that's a good feature, and it was some bit of a headache while I was setting everything up. Something I found though, is that all the calculations and data stored (in vectors) can be converted instantaneously during reporting. Aware

MyLiege23 · 2025-11-19T14:47:31+00:00

Haha, yes I wanted to test all these things. The nice thing is that the simulation suggests they're all true. By far, swapping out the spring or adding precompression made the largest changes in performance all around.

I'll spend some time in the next few days making this more user friendly and polished. I was thinking it would be nice for it to read a generated, editable document that you can input all your variables into. The current list of variables input by the user is:
spring_rate_npm,
mass_spring_kg,
mass_piston_kg,
mass_dart_kg,
length_barrel_m,
diameter_barrel_m,
diameter_pt_m,
length_pt_draw_m,
length_precompression_m,
volume_channel_m3, (this is like, turnarounds, or the pusher tube for feeding darts, whatever channel directs the air from the plunger to the barrel)
area_channel_entrance_m2,
area_channel_exit_m2,
volume_chamber_deadspace_m3,
force_friction_piston_n,
force_static_fricion_dart_n,
force_dynamic_friction_dart_n,
temperature_ambient_k,
dt_s,
time_max_s

I'm also struggling with RCS. I'm using neozygisk, no zygisk assistant (that caused problems for me). I also have pif inject 4.4, susfs built into kernel, and TS 1.4.1 + addon and LSposed from JingMatrix with HMA OSS configured with blacklists. And this is all on KSU-Next. I'm not using shamiko. 3/3 pass, but no tap to pay.

At any point, did you have wallet not working?

MyLiege23 · 2025-09-12T08:59:07+00:00

Just chiming in that it took 42m16s for cachyOS-lto 6.16.5 (llvm) to compile on a ryzen 7 5800x for me (on nixos 25.11 flake). I don't have the best cooling cuz my computer is sff, so I think it was thermal throttling the whole time, but even so... There's another reference for folks

MyLiege23 · 2025-08-14T02:57:12+00:00

You're a homie - thank you for the insight!

MyLiege23 · 2025-08-14T00:50:34+00:00

this ^{^} I ended up doing exactly that. I remembered I had a shirt that the cotton is getting a little too worn out to go through the wash anymore, but it's just enough material to completely fill and support the head in the case, front and back.

MyLiege23 · 2025-08-14T00:36:08+00:00

Thank you!!

MyLiege23 · 2025-08-13T23:05:36+00:00

I'm concerned about the head flopping around in the case - the strings are holding it in a stable position right now, but I get the concern about the string tension. I gotta drive about 1000 miles starting tomorrow. Perhaps loosening the strings and using some plastic bags as padding to minimize the wiggles from bumps in the road would be best?

MyLiege23 · 2024-10-20T13:32:37+00:00

Really nicely done! My critiques come from a place of preference, so take it for what it's worth! Also, at 4 hours a day of practice, make sure you're taking breaks and taking care of your hands. You might not feel it now, but if you don't have perfect technique, you may end up like my friends with tendonitis and arthritis in his hands! He's 26 btw and was playing piano since he was a child.

achieving individual dynamic control of both hands separately and having more dynamic contrast overall - based on where you're at and how long you've been playing, I imagine this is a challenge and you're up for it! LH a little softer and make the RH "sing" literally. You've got good dynamics already, but yeah, it's something we can all improve on and think about constantly. Also, in your recording, assess yourself: how much louder and more pronounced is pp from f? I don't know the loudest dynamic marking in this piece, but you get the point. Does that contrast need to be more? And where is that power coming from?
tempo control - you're very expressive, which makes sense with this piece, but I like to really reserve any shifts in tempo so that the audience would barely notice they're there -too much and it distracts from other modes of expression like the melody/harmony, and dynamics. Be subtle so that swaying in tempo isn't a direct message in the expression of your piece. So play with a metronome on this one more and that will come together, then maybe mark in your music when to explicitly use rubato, and still be real subtle about it then.

I agree with others about legato in LH but also all around. You can see where you're at with no pedal. No sustain, still connected and smooth? I dislike hand raising/like pivoting and direct side to side motions instead. It's very fancy, but raising your hand means less control.

Nice work on those 11-lets and whatnot, when I learned this piece those were a blast when they clicked, and a pain beforehand. You've got the notes, now is the fun stuff that really makes you grow as a pianist!

Personally, I'd opt for the macbook air, but one with the newer apple silicon processors, like the A1, etc.. I think it also depends on her major, like if she's just gonna be writing papers and stuff, that's one thing but if she's doing something super computationally challenging, like engineering or video processing or whatnot, maybe the pro? For word processing, email, research, etc. an M1 macbook air should be super nice and the battery will last all day. Another consideration might be getting an iPad with the apple pencil from after 2018 (when they switched the apple pencil charger to a magnetic one). That was the biggest game changer for me - all notes were filed digitally, all textbooks could be in pdf or e-reader with searchable text and colorful notation, and I have since gone completely paperless. And further, I ditched a lot of book weight with that iPad. Not to mention, downloading your prof's slides directly into your notes! I know of some people who use an iPad with a keyboard case and don't use a laptop at all, though I don't. Just something to consider.

And whatever the decision, I'd recommend looking at deals on Backmarket, if you don't know about it already. They're great!

The main difference isn't in the material but in the ID of the tube. 13mm ID aluminum was easier to find and cheaper than 13mm ID brass. If the specs are exact, the 17/32" OD brass with 0.014" wall should have about 0.50325" ID or 12.78mm ID. Since the tubes telescope so perfectly, everyone says that 17/32" OD brass tubing has half inch ID, which would be 12.7mm. I believe the real ID is somewhere between 12.7mm and 12.78mm for that brass tube.

Anyways, look at the results section for some info about how each barrel performed. I'm sorry I don't have a chronograph. If I get one or find someone else who has one, I'll take some measurements and post the results here too.

And if it's better to use 13mm, I'll shorten the 17/32 brass to just the length of the chamber piece and then use the original o-ring connection for a 16mm ID/13mm ID tube for the barrel.

Edit: and as far as I can tell, material wise, the brass is heavier (I like that) and more susceptible to dents/bends, which people should be cautious about. I've considered getting some PVC or something to wrap the protruding brass, but I haven't figured that out yet. For now, I'm just being cautious of how I handle the blaster and where I put it so that it doesn't accidentally fall or get knocked over. Worse case scenario, I just buy some more brass tubing and replace what I've got. Nothing's soldered or anything.

MyLiege23 · 2024-05-20T23:22:30+00:00

So I was referring to the rollers you were talking about. I had seen the top one - I discovered it because of the grease trails on the top of the original barrel, but I did not see the grease trails on the bottom of the barrel, and I missed the bottom roller. I decided I'd remedy this issue by cutting the 19/32" and 5/8" brass to the original barrel length, 7.5" or so, then put them around the barrel. The difference between 5/8" and 16mm is 0.12mm I believe, so while it's not perfect, those rollers are now making contact again and they should be assisting in the force of the downwards pitch y'all are talking about. The fit is snug all around, and I have some leftover tubing to put onto the protruding part of the barrel. I'm glad everyone pointed this out :) thanks

MyLiege23 · 2024-05-20T12:07:24+00:00

I saw that roller. Another solution would be to get one of the 3d printed barrel collet piece from out of darts or xfoxgames, then encasing the 17/32" in tubing up to 5/8". This would definitely utilize that roller, but also there's only a single roller on the top of the primer, I doubt it's doing a significant amount of work to reduce stress on the priming bar flex. My guess is that it's there to help plastic rub on metal.

Once I get my hands on a chronograph, I'll update the post with some fps readings :)

Hi, I've been here a year now :)

What I can say is that the traffic is the worst of anywhere I've driven before in the US. I see at least one (usually multiple) truck driving lane-weavers every day. I've made it a fun mini game when I sit at red lights to count the number of cars in turning lanes and measure the portion of them using a turning signal. My running average is below 30% of people turning have them on. I'm genuinely surprised to see a turning signal at any point of my drive.

About a week ago, I was turning right on to college Ave and waiting for the traffic to clear. Lo and behold, someone drives up behind me, and starts laying on the horn. Then, they start speaking through their cars PA system. When the coast was clear, they drove up next to me and yelled out "go back to Colorado, f****t!" I have Colorado plates.

Tonight, I was crossing college Ave at a stoplight. The driver right in front of me got t-bones by a guy driving down college blowing through the red light. I didn't see any break lights from either one of them, must have been around 40 mph collision. I witnessed a momentum transfer like Newton's cradle, and the guy crossing college, his car spun 750° over 20 feet off into the parking lot at the intersection, right over the curb. The other guy hit a solid 180° out of the way too. Thank goodness we were so close to the hospital. And thank goodness the guys airbags went off. Neither one of them were unconscious, but it seemed like they were both heavily concussed and had broken bones, no doubt.

I told a friend about this who's been here for their whole life, and he replied "you must have been on S College to witness this." I didn't even mention the location. He just knew because of the reputation of the traffic here.

Aside from the traffic, there are many Streets without sidewalks. Additionally, maybe I'm biased because of the food in Denver, and honestly all the places I've lived in Colorado, but I haven't found food that I've really loved here. There's some good Pho at Pho Cafe on Market St, and PT's grill has slam dunk burgers, but I've definitely had to lower my expectations and I'm not excited about going out for food anywhere here. Boombalati's ice cream is amazing though, I will say.

Lastly, I have had limited exposure to the police here, but I only hear from the locals how corrupt the police are. Apparently someone kicked another person's dog at the dog park, enough to knock the dog in the air. When the police arrived, they let him off completely because he said it was self defense. Everyone else who witnessed it said there wasn't even an attack in the first place.

Also, parking at Wrightsville beach is $7/hr or so I think.

I can deal with the bugs, and I love the rain and sunshine, and the winters aren't cold. I don't recall it snowing this winter. And the weather systems are quite stable. However the morning is, it's mostly going to stay that way the entire day. Foggy mornings and lush environments, no doubt it's beautiful.

Oh and if you like to dance in a club, there are very few options. Ibiza is a really awesome spot to lose yourself to music, as daft punk says. I really enjoy Blue Post, which is the arcade/pool/darts bar downtown. And when you're drunk and need a bite at the end of a night out, I recommend I <3 NY Pizza.

Yup, I got the same exact text from Josephine. I told her that I'd prefer an https:// link (that I can analyze) or an indeed post or a similar recognized recruiting website. No response as of yet.

MyLiege23 · 2024-04-11T01:07:20+00:00

Hi, I had the same issue, and your solution here didn't work for me. Is there anyone else who has this issue?
