Both my first custom design and first print on my personal printer! A case I designed for a power supply tester I made on a 2" protoboard. The base and case are fairly generic, with a hole in front for an LED, back left open for heat sink. The top cover is a little more specific, and fit the adapter that I needed. Held together with 3" 6-32 machine screws.(4x) 3" 6-32 UNC Machine Screws (4x) 6-32 Hex Nuts (4x) Rubber feet When I printed it I had to drill out the screw holes and the hole for the LED, but have since increased the hole sizes. Only actually needed one of these so haven't printed to check the new clearance... if something doesn't fit, grab a drill. Slot for protoboard was also a tight fit, but with a little pressure it will slide into place.
