This is a Variable Power Supply which uses a laptop power brick. The case requires no hardware but I did superglue the front and back faces on. The buck converter I used is from Amazon.
I use ferrule and Spade connectors so no soldering is required. Make sure the wire you're using is capable of handling the current you plan on using.
Updates:
Added Step Files: please let me know if they are trash. This was originally designed in Tinkercad and I imported the STLs into OnShape in order to export the Step Files. Not sure how useful that is. Ultimately I'm going to use this a learning object for OnShape or Fusion.
Added a version 2 of the faceplates and body the previous version had to be glued. The version 2 has 4 clips which secure it in place with no additional glue or hardware needed.
Reduced the dimension of the faceplates by 0.1 mm to provide a better fit.
The version 2 faceplates can be removed by gently prying with a screw driver from the top or bottom edge and then working around the perimeter of the plate.
