30 amp power supply case/cover

thingiverse

I was searching for a 30amp cover, but all I could find were covers for lower current supplies, so I designed my own from scratch. My initial design was based on a 1mm template, which I adjusted after printing to accommodate the screw mount holes for the switch. It printed quickly at 0.3mm resolution and turned out great, with a wall thickness of 2mm. The small plugs that need to be printed if you don't use all three cable holes came out perfectly fine. The extrusion mount was designed with a bit of extra room for the mounting holes and the center hole is 2.8mm, just right for the 3mm screw to bite into securely. This design has been tested and works flawlessly. I purchased the switch from Amazon: https://www.amazon.com/dp/B00ME5YAPK/ref=oh_aui_detailpage_o04_s01?ie=UTF8&psc=1 The PSU measures 21.5x11.3x5cm in size.
