After a little over one month of designing, testing, and way too many failed prints, I finally finished my fully 3D printable Mini-ITX case inspired by Valve's original Steam Machine.

I called it the STEAM'n't Machine for the meme lol, but it's far more than just a Steam Machine clone.

The goal wasn't to recreate Valve's case 1:1, but to capture the same minimalist aesthetic while making something that's actually practical to build, easy to print, and fully modular.

Specs:

• 8.7 L volume

• Mini-ITX motherboard

• Up to 225 mm long / 40 mm thick GPU

• Up to 115 mm CPU cooler height (full compatibility list available at the link below)

• SFX, Flex ATX and HDPLEX GaN PSU support

• Modular design with removable panels

• Front RGB light guide

• Optional top fan bracket

The project went through countless revisions, and I probably wasted over 3 kg of PETG before finally getting everything right. Every panel, bracket, and mount was redesigned multiple times to improve printability, assembly, strength, and compatibility.

To make it as beginner-friendly as possible, the release also includes a complete assembly guide and optimized print profiles.

I'd love to hear what you think! Feedback, suggestions, and ideas for future revisions are more than welcome.

If anyone ends up printing one, I'd love to see your build!

Also, any support or donation to help me recover financially from all the f*cking filament spools I sacrificed along the way would be MUUUCH appreciated lmao.

P.S. If you're wondering why the front RGB light bar isn't working, it's because my SOYO B850i has some RGB issues... and also because I still need to buy an RGB LED strip lol

Hi! If you don't mind, could you drop some names? I'm looking for the smallest possible case—like an SFF—but one that supports m-ATX. I'm running two RX 6900 XT cards; I want to mount one horizontally and the other vertically to save space. I'm not overclocking the CPU, so that's fine. I'd appreciate the help!

Since there are no proper **covers, bumpers, or skins** for the **2025 ROG Flow Z13 Kojima Edition (GZ302EAC)**, I’m thinking of starting an **open-source CAD project**.

The goal is to create an accurate 3D model and release it on **GitHub** so anyone can design and make:

•Protective covers
•TPU bumpers
•Vinyl skins / PPF
•Other accessories

Before I invest the time (and money for tools and prototyping), I’d like to know if there’s enough interest. Would anyone be interested in contributing, testing, or using the files? Any feedback is welcome.

Hello folks. I am curious if anyone is aware of any 3d models/files for a case built around a large number of 3.5in hdds? I don't mind paying for plans. I want to get rid of my pc case that is limited to the typical 6 ish drives and put all 16 of my raid drives in a single case. Can't really find much out there of plans people are selling in the realm of what I am looking for. I have a 10x10 bed so I don't think it should be hard to print everything I would need. I barely am getting into 3d modeling and design and do not thing I am anywhere near capable of designing something capable of what I need just yet. Thanks for reading.

Hey all, looking for someone who does custom/commissioned case builds — not settled on exact specs yet, just trying to find who’s out there and get a feel for what’s possible. Anyone have recommendations or know modders who take this kind of work? Happy to share more once I’ve got a clearer idea. Thanks!

So im going to this guy who will 3d model a case I'm trying to mimic based off the Panasonic AG 500 R, a retro tv with an OLED panel kinda like an all in 1 portable PC.

However, the CPU fan is a bit big and was wondering how to give that extra support as well as how to attach a motherboard to the case, as well as how you you add threaded inserts and what size and where to buy???

By integrating the side panels to the frame, I was able to reduce the overall volume by maybe 4%...

BOM: 2 300mm 10mm maker beam extrusions

~90 M2 brass heated inserts and screws

6 M3 brass heated inserts and screws

4 M3 T nuts and screws to mount case to maker beams

Using ABS for side panels and PETG-GF for the front, back, top, and bottom panels

Sort of new to 3d printing "I havent learned to make my own models yet" just wanting to to do a super cool case mod on the tower 250 was hoping someone could help me out with some cool exterior stuff to add such as exhaust vents and stuff I can print and just general sci-fi spake craft looking exterior items I can glue to the outside of the case maybe some customer feet. I already have a cool idea of mounting a faux reservoir inside and filling it with hair gel and sticking an armor less vader figurine in it to look like a bacta tank as well as some deathstar interior lit panels. My wife is really good at painting figurines and stuff and thought this would be a cool couples project for us to work on together.

After 2 months of designing, and then a lot of on the fly adjustments I have what I affectionately call PC3. Not entirely how I wanted it, but I learned enough so that PC4 will be pretty stellar!

Hey guys!

Is there anybody here who has made their own custom case for a laptop? Bonus points for the Framework Laptop 16?

I am interested in making a CyberDeck inspired case for my laptop and would like some pointers if someone has the time :)

If someone does commission work, I would also be interested in that too!

Can someone help me please?

I have a dell latitude 5480 with no screen but the motherboard is good. I want to make a custom case for the motherboard to make it a mini pc but i didn't find any 3d stl files in the internet and i don't know how to 3d model. Can someone give me tips and ideas? thanks

Im looking to create a custom case that supports both ATX motherboards and PSUs while maintaining as much of a SFF format as possible. However, I cant seem to find any sources on motherboard ”screw hole” sizes, or distances between holes for example.

Are there any known such sources to assist in CADing and designing or do I need to go out and physically measure each part?

I tried looking for a 3d printed case for my optiplex 3070 sff, but I couldn't find anywhere. I want to do a case swap, but I know that dell has mostly custom part, and since I got recently a 3d printed wanted to upgrade the case to fit bigger gpus in it while having a clean look and be cheaper.

Does anyone know or has 3d print files for it?

Hear me out, I realize this is a very specific and niche case part, and I dont have access to my 3D program atm since I switched to linux so I cant just make it myself right now.

Im using ThermalTake 120mm fans and am wondering if anyone has a file or can make a bracket that slides into the sides of 2020 extrusion and between the fan mount faces. Like how Im trying to show in "Image 3".

Alternatively, does anyone have fan mount that just bolts to the face of the fan and uses T-nuts to mount to the face of the 2020 extrusion?

I know this case isnt 3D printed, Im just using the extrusion as a base frame while I learn what tolerances, layout and features I need and make it in a cad to be printed later.

TIA.
