A housing for some PWMs I got from ali express (e.g.: https://www.aliexpress.com/item/Free-Shipping-DC-New-1-8V-3V-5V-6V-12V-2A-Low-Voltage-Motor-Speed/32610905123.html?spm=a2g0s.13010208.99999999.283.x3ftfS) .

The bottom has small clips that mate with small slots in the top piece.

M2x4mm screws can be used to attach the board to the lower piece (probably up to 6-7mm length would work). 3mm holes are in the upper housing to attach the entire assemble to something else.
