This is a full rebuild of the @ManelTo cover.  Starting with the r3 version from Prusa.

Link to Amazon (USA) power supply and USB circuit board that I used (still same 15W).

Additional parts needed;

  1. M3x8 Screws (Qty. 4)
  2. M3 nuts (Qty. 2)
  3. M3 square nuts (Qty. 4)
  4. Terminals to connect to Motherboard Power IN terminals.
  5. Soldering Iron & Solder.

Printed with Polymaker PETG (black).

3 walls, 15% gyroid infill - no supports needed.

The square nuts are a snug fit (without supports), but they will fit.

Your wiring may look differently as I am also powering an LED bar from these same terminals on my printer.

***I had some left-over parts/pieces from this project, if anyone is interested in complete, bolt on versions, I have a few for sale at my Etsy store.***
