Bench Power Supply

I designed and printed a case for a benchtop power supply following this project: https://dronebotworkshop.com/simple-supply/

I designed mine to have 3.3 and 5.0 volt outputs from two buck converters, and a variable output from a DROK NC Regulator. Common ground jack for all outputs.

Cost of purchased components is about $70. I used an old laptop power brick that I had in my workshop. If you don't have one of those, you'll have to buy one. Be sure that you have a jack that is compatible with the power brick you have; some jacks are hard to find.

Total print time is about 8 hours.
Post printing cleanup, assembly, soldering, and testing is about 6 hours.

Print Setup:
Prusa MK3S Printer

Main Case: 0.6 mm nozzle, 0.20 layer height, PLA, painted "snug" supports on DROK opening, side openings, test leader holder, front panel marking cutout, and fan switch cutout.

Top: 0.6 mm nozzle, 0.20 layer height, PLA, painted "snug" support for jack cutout.
