ATX to SFX PSU Adapter
This is an ATX to SFX adapter I used on a Sugo SG13 case. The screw holes are auto-threading but you probably better use some thread-lock glue.
I printed it on an original Prusa i3 mk2 in ABS. 0.15 layer height. Very easy and quick build.
The holes on the bottom are for ventilation.
