Here is my version of a case for the very popular (and cheap) IRF520 MOSFET module.

I am using this MOSFET for switching on/off a 24V lightbar by a 5V signal.

The Input power connector has a diameter of 8mm the output male connector is a 2.54mm JST connector.
The signal input is a 3 pin Dupond female connector.

After soldering the wires to the 2.54 mm JST male connector I fixed the connector with a very small amount of superglue and the used hotglue to make sure that the connector will stay in place.

You will also need two 3mm (2.9mm or al little less sould also work) screws with small heads. The length should at least be 9.5mm.

Support is onyl needed for the case. To prevent all small holes from being filled up with support I set the "support overhang angle" to 80 degree (in cura) This worked fine for me.
