I was in need of a reliable power supply for my maker space. I need two adjustable outputs, constant voltage/current, and voltages from 3.3 up to 30 V. Having 5A was one goal as well.

3D print all the parts once each. Forget about support, rafts, brims etc. Just 3 shells in each direction, and 20% cubic infill. I used standard PLA from https://dasfilament.de, and the stuff printed well on my Prusa I3 Mk3. If you have a printer with less then 250mmx200mm print bed, this thing might not be for you.

Once you have the printed parts available, and sourced the list above, this was my way to go.
