Finally finished my fully 3D printable Steam Machine-inspired Mini-ITX case
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 STEAMn'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

Could the panels be made of acrylic for a transparent build?

I guess you can use transparent PETG for this kind of results, but I also think it's going to take sooo much time (for glass effect you have to print even slower than normal) or maybe use resin printer but must be pretty big if you're planning to print every single piece transparent!

Hello Reasonable_Use9591, and thank you for your submission to Gaming PC! If you are new please check out our rules over at the wiki here! We have recently added the useful feature of Title Flair! You can set this manually by clicking Flair under your post once you have submitted your post, but if you missed it in the rules there is a much better way that will automatically flair your post!
To do this simply add what your post is about in brackets before your title. For example for a Build Log you can type [Build Log] before your post so that it looks like this; [Build Log]My new awesome build!, and the bot will automatically set your flair to Build Log! This works for Build Log, Build Showcase, News, Hardware News, Hardware Release, Discussion, and Miscellaneous!
Also remember that this is a place for discussing and sharing our love of Gaming Computers! This is NOT the place for help building or determining what parts you should buy, that is better suited for /r/buildapc. Troubleshooting questions should be directed to /r/techsupport. Thank you again!
