M6 Hex Nut Cover

I wanted a cover for exposed connections on my backup 120V inverter. It uses an M6 screw/nut so this is just a cap to cover the exposed connections. Hole is big enough to rotate around the nut and the threads are M6. Fusion360 file is there if you want to modify anything.

Printed with PETG 0.15mm and 6 perimeters to make it mostly solid.
