I've got a lab power unit at the workshop. I've created a box to cover it on a Multiboard wall, and needed a way to cover the power plug. So this cap can be easily hung on a Multipoint. It keeps the plug clean in a dusty environment.

Use a Multipoint as hook to hang it onto.

Update v.1.1 April 21, 2025

Added 0.2mm more clearance on all four sides inside the cap. Mine broke after a few sliding in and out of the power connector, since it was just a little bit too tight. Now it seems perfect.
