I wanted to add a DC to DC converter to my Ender 3, to power a 12 volt fan. I tried another LM2596 Buck Converter case, but the dimensions where slightly different. So I designed my own case.
This case comes in two parts, and you will need two M3 bolts that are about 16 mm long.
The Base:
Choose either a plain base (Base.stl) or the base that slides onto the 2020 rail (Base w Rail.stl).
The Top:
Choose either the top with one larger hole at each end (Top 2hole.stl) or the top with two smaller holes at each end (Top 4hole.stl), depending on your wiring needs. The top fits on one way, as the adjustment pot fits in the access cutout. The voltage IN and OUT are marked, along with the polarity.
Note: it seems like not all LM2596 boards are the same dimensions. I only have one style to test with. I included photos from the Amazon.ca listing, which I bought. I can't guarantee that your LM2596 will be the same dimensions.
Also be sure to rotate the models, so that the grill is down, and no supports will be needed.
