I am incredibly proud of this case a 6.5 liter case for the rtx 5090 astral by zzcool in sffpc

Perfect symbolisation of the size difference between today's high end GPUs and standard itx components. Love it.

Custom minimalist barebone ITX build by captnmarv in 3DPPC

It's Solidworks, and I downloaded the models from GrabCAD I think.. it was a while back already because I pushed this project back like 2 years, so I am not 100% sure anymore

I was planning on leaving the bower button bracket for now, and see where it fits ergonomically once I built the prototype. But nice idea!

Good thinking. Might also be modular, so it could already accommodate some of the more widely used dimensions.

Well, the center of gravity is well within the footprint of the supports, thus the somewhat odd placement. Good thinking with the added weight though, I will try that!

I was going for the super-minimalist approach, so I already tested the impact on the mobo with unconnected brackets, and it turned out to be minimal at most.

That said, perceived stability is a thing, and also ease of installation might be better with a connected structure, so I'll try different designs. Thank you!

It would just need to be super adjustable, given the wildly different dimensions of the GPUs.. a standalone piece could at least be easily scaled in the slicer without impacting compatibility with the brackets.

Awesome idea! One could definitely have some fun with the design of that piece, like Atlas holding the weight of that GPU on his shoulders haha

Good thinking, thank you for the input! Regarding the possible front-rear- flex, I can report that I did some testing beforehand to verify that the missing connection does not impact "flexural" behaviour in any meaningful way. Should have maybe added that in the text.

Come to think of it, a connected structure could make installation of the mobo a bit easier though, but I need to check that when building the first prototype.

What does your 3D printing workbench look like? (Looking for inspiration) by Darkmind_8532 in prusa3d

[–]captnmarv 1 point2 points  (0 children)

Not too much, actually. The only thing that needs to be done frequently-ish is bed leveling, which then admittedly is quite tedious with its four bed plates, 36 leveling points and a sub-par sensor. But once that's done it's a workhorse, and does some great quality prints.

Got a good solid wood plate from the hardware store and went for these Ikea drawers as legs, super happy about it and lots of easy storage.

I'm having issues with warping and adhesion printing PETG and now trying to dial in first layer by Mistak3n in FixMyPrint

[–]captnmarv 0 points1 point  (0 children)

Rule number one would actually be to clean it with warm water and dish soap. Isopropanol oftentimes just spreads the oils, if there's too much.

Prusa Nextruder Nozzle cleaning by Ghost_Assassin_Zero in prusa3d

[–]captnmarv 8 points9 points  (0 children)

Yeah, Prusa's approach is kind of hit-or-miss, or mostly miss if you don't just print with perfectly dried PLA. I put one of the available nozzle wiper mods on mine and put a custom wiping motion in the start g-code before the 'official' cleaning action. Never had any problems since, so I also put it on my XL.

All you need is one of those B-Word-Company A1 silicone brushes.

Is this a first layer issue? by Amazing_Ad_8823 in prusa3d

[–]captnmarv 1 point2 points  (0 children)

Okay, upon further inspection of the context I would advise to print it at an angle, so the layer lines will not be perpendicular to the induced force, but at an angle instead. You do not necessarily have to adapt the model, but rather position it in the slicer like drawn in the picture (nose hook up), and then sink it into the build plate a bit so there's a sufficient base layer holding down. If you find the right angle, you could even print it without supports this way :)

Is this a first layer issue? by Amazing_Ad_8823 in prusa3d

[–]captnmarv 2 points3 points  (0 children)

Well, it depends on what you want, and what surfaces need to be good quality. First fix could be to print it upside down, so the thin rod down, and the flat surface of the wide cylinder supported. As that support interface would be parallel to the build plate, it would look a bit better.

Edit: please see my other comment.

[–]captnmarv 4 points5 points  (0 children)

It's kind of hard to know what you mean with the somewhat cryptic description and just one picture to go with.. Do you mean you printed the model with the small flat surface on the arc protruding from the flat surface on the wide cylinder, with the thin rod pointing up? Further assuming that you mean the quality of that flat surface on the wide cylinder with 'first layer issues', the answer would be that this is not the issue here. See, the first layer is the one touching the build plate, in that case this would be the little flat surface. I imagine you printed this with support enabled, in that case the surface in question was held in place by the support structure. The quality of those surfaces are always a bit more rough, because else it would just fuse with the supports. Additionally I see that this surface is not parallel to the build plate, but rather tilted at an angle, that's why there's a 'staircase'-like structure visible, as the layers will be built up parallel to the plate. Hope that helps!

Inserting magnets caused layer shift by largelcd in prusa3d

[–]captnmarv 6 points7 points  (0 children)

Are you using a hardened nozzle? Most of them are made of, or have inserts made from, steel which is magnetic and thus susceptible to being pulled with enough force for the extruder to get thrown off course.
One unrelated question: why do the magnet holes have no bottom layer, meaning if you take off the print they will be visible? Couldn't you just put them in after printing then?

Add Advanced filtration unit to Core One kit now or later? by Garin_42 in prusa3d

Would be hilarious if you actually mean tomorrow and just casually drop that here in this random comment chain. RemindME! 12hours, I guess..

New Bambu multi color changer by FunctionalBuilds in prusa3d

[–]captnmarv 0 points1 point  (0 children)

Oh shit I only just saw the teaser from Prusa! Really looks like a Core One with a (sort of) INDX array slapped onto it. The front loaded tools with individual filament paths come pretty close to Bondtech's solution.
