This is a small form factor PC case that I designed to house some re-used components along with some new parts for a PC build intended as a "console" like PC that is in my living room.This should fit any mini itx motherboard with a 53" low profile cooler, but my parts list is below for reference. It is also designed around a normal ATX power supply, as that's what i had available.

The parts are designed to require minimal post processing. There should be no supports required for any parts. I used M3 brass threaded inserts for the fan mounting holes and M5 inserts for the feet mounts, some simple redesign of the mounting feet could allow a much easier pin/hole attachment. Panels have a tight tolerance press fit together with poke yoke'd dovetail joints so panels can only go together one way.

I used a 0.8mm nozzle to print, so be aware that the 3mf has some print settings that would need to be adjusted for smaller nozzles. For the main panels I used 0 top and bottom layers with 20% gyroid infill. I have custom modifiers designed into the parts for the sections where i added 3 top and bottom layers back in for strength or to block view of parts.

For materials I used Creator Midnight Blue ASA-CF for the main body, Creality Hyper PETG Clear for intake grill, and Siraya Tech TPU Air for the mounting foot isolators. I had the ASA-CF collecting dust and ASA is great for high temp applications, however, if i were to print it again I wouldn't have used that brand. It's got some really bad layer bond strength, so snapping parts together without damaging the dovetails was a challenge. The PETG prototype parts I made would have worked much better, and in reality the softening point was much higher than I would see in use. I would not recommend PLA for this build. TPU Air definitely not required for the mountin feet and PSU isolator but it is a very cool high performance material!

Parts List for my build that are confirmed to fit and work!

Thermaltake CT120ARGB Cooling Fan 2 pack (any 120mm x 25mm case fan should work) intake up top, exhaust on bottom
ASRock A620AI AM5 motherboard (Any mini itx motherboard should work and mount, check back plate opening and heat sink clearance)
Thermalright AXP90 X53 CPU Cooler (low profile coolers up to 53mm height off cpu should work)
DDR5 Ram (no heatsink on the sticks i used)
AMD 8600g APU (8500g/8600g/8700g will work - integrated graphics required as i did not design for a dedicated gpu!)
- Wraith stealth cooler that comes with the 8000 series APU's is perfectly acceptable for this build, I chose to use a different one for improved cooling, but not really necessary.
For power button i used a momentary push button thats available at any autozone, wired to some dupont connectors.
