Advice Calling my friend up for a favor [mATX case 3D print]

[Hismuth]

So basically, my friend owns a 3d printing shop, and as of recently, he offered to print me whatever I need as a payback for a favor. So I am planning to 3d print a tiny mATX case that can house the following:
- 240mm AIO
- ATX PSU
- NO support for 2.5 inch storage
I was hoping someone has some sort of a 3d project available, as I couldn't find anything other than mITX cases, and I don't have any sort of background in 3d designing.

I would suggest not going the ATX PSU route and instead have it built for SFX PSU. You can then in theory have more space for your parts.

This is probably not quite what you are looking for, but does show that a small mATX case can be 3D printed.

It is only 11 litres, but the graphics card positioning may be a compromise too far.
