I wasn't thrilled with the price of the very small SFF cases so I decided to take a stab at designing one myself. I already had a parts list in mind so this isn't the smallest I could make it, but had a few qualifications in mind.

1)Printable on regular 3D printers. I designed this initially to print on a Cetus3D Extended, but also kept it in line with a Creality Ender 3. Printed dimensions 147x179x250mm (6.58L)

Have as much as possible 3D printed. Only thing you need is standoffs for the PSU, a power button, and a PCIe Riser if you want a GPU. You could probably mount several 3.5in Drives where the GPU would go, though I didn't try. Depending on your PSU standoffs, you may need a right-angle power cord.

Print with zero supports. Hate removing them, so design around them.

Needed to hold an ITX GPU (~170mm), 70mm CPU cooler, and SFX PSU. Only officially supports M.2 drives.

Minimal Assembly. Prints in two parts which can be attached with case screws, though not needed.

C14 Socket (if you want to hard mount power cable): https://ebay.us/vokHEd

CPU Cooler- Scythe Big Shuriken 3: https://ebay.us/oz8pHu

Extended version adds space for 1 120mm fan (or 140mm fan with 120mm holes). Interior remains the same. I used this fan: https://ebay.us/OR1Akb

Notes:

.3mm Layer Height

4 outer layers (Could go less, but since we are screwing things into plastic I went the safe route)

20% Infill

No Supports

At 60mm/s (.4mm nozzle) inside takes ~17 hours, cover takes ~38.

Will use ~0.8KG of PLA. ~0.5KG for cover, ~0.3KG for interior.

Other than PSU, everything should mount with case screws.
