Bench Power Supply
Picked up a cheap computer power supply and printed a lid with some holes for switches, an indicator light, and 4 binding posts. 3.3v,5v, 12v for under $20. And plenty of amperage. In hindsight, wished I had put a USB charging port on it while I could. The piece was a 6 hour print, so doubt I will re-do with the port.
I included the 123D design file so you can move your screw holes as needed.
