A simple snap fit case for the LM2596 DC-DC converter to use in my Ender 3 as a motherboard fan controller for a Noctua NF-A4x10 FLX fan.
This housing is designed to be just small enough to fit on the right side of the motherboard. I know there are some different pcb versions around. I have one where the center of the trimmer is 18.5mm away from the center of the hole on the left side.

2 M3 bolts are used to secure the PCB to the case. Because I didn't have shorter bolts then M3x8mm available I've added some spacers.
If anyone decides to make this I would love to see some pictures!
Edit: I've noticed there was a small error in the model of the cover I uploaded. There was a wrong wire cutout and it should be fixed now.
