A 2 MOSFETs case for Creality Ender 3. It is attachable on the power supply. I let the MOSFET heatsinks to be visible (the 2 rectangular holes) and you can check the temperature. But they are cold in my case.
This is a version 1.. I made 1 print and debug the major problems. I published also the *.ipt files, so feel free to modify.
In the end, I just drilled 2 holes next to the heatsink to see the indicator LEDs. It is not in the model.
You will need:
2x M4x8 bolts
4x 3x30 twinfast screws
4x 3x10 twinfast screws
