Bench / Desk Top Power Supply

thingiverse

Inspired by Ben Heck, I built my own bench top power supply for testing devices. I salvaged an old slim ATX power supply that could output about 300 watts and pruned all the wires on it to clear up clutter, using only the essential wires. Please note that I utilized a compact ATX power supply shorter than standard units. I've included the SketchUp file so you can expand the base to match your power supply's dimensions. Here's the configuration from left to right: 12V 5V 3.3V Ground You can achieve various other voltages by combining positive leads, as I demonstrated in the photos. For this project, I relied on items I had lying around: A 5mm red LED for a status indicator - available at Radioshack.com A 100 ohm resistor for the LED - found at Radioshack.com Banana Jacks from Radioshack.com Solderless Banana Plugs for leads also from Radioshack.com Instructions I utilized red ABS with arch chords as the infill and top/bottom layers, filling it 30%. I bonded the layers together by painting them with acetone. Once that was complete, I spray painted it silver.
