This is a cover that goes over an upgraded power supply for my Anet A8 printer. The cover is attached to the PSU with a pair of computer case screws. The switch fits snugly into the cover and is attached with some more screws. This file is designed for the two specific components below and may not fit on other, similar parts.

This upgrade was added to make my Anet A8 safer. I've put together a video describing all of my safety upgrades here: https://youtu.be/MzWVrv4L1R0
