This is an enclosure based around my (vague) memory of the Amiga PSU's (I also have one for Amiga 500/600/1200's). This enclosure is designed to house a Meanwell RD-35A power supply, and includes cut outs for an IEC connector (aka Kettle cord) and a switch. The switch isn't really necessary for the CD32 - but I like saving a bit of power by turning my powersupplies off.
Print the lid with the top down, the base with the bottom down, the cable clamp with the "grip" up and the logo plate however you'd like. Use supports with an XY separation of 1.2+mm (so it doesn't put supports in the vent - the vent will print without supports just fine).
And please post makes!!! I had about 3 goes at printing a red version (in pics) - but the lid kept stuffing up. I think (a) it's dodgy filament and (b) my PEI might need a wash. Worked fine in black - so I'm blaming the filament.
The extra parts needed are (as near as I can tell - I bought my parts from Jaycar in Australia - though they didn't have the 4 pin DIN):
4 x Large screws (Join lid to base) 2 x Small screws (For cable clamp) 1 x IEC Socket 1 x 240V - 10A Switch 1 x CD32 4 pin DIN 2 x Mainboard Screws 1 x Meanwell RD-35A 4 x Rubber feet - 12mm
