30A relay case
thingiverse
A case for a large 30 Ampère relay that I am using for PSU control on my Ender 3. A 10 Ampère technically isn't quite enough for the highest possible power draw, and I just want to be safe. I'll probably make or find a flat print with T-nuts attached to attach to it using acetone. Requires quite short M3 bolts fort attachment, but could also be hotglued. Be careful with mains electricity!
