Promega PSU switch box
thingiverse
I'm not a fan of a permanently powered-on power supply, so I added a simple toggle switch. This uses the holes that had zip-ties for the original power cord with 8mm M3 pan head screws and heatserts, and a standard power cord. It works perfectly! I repurposed an old power cord from somewhere and a cheap fused switch from Amazon: https://smile.amazon.com/gp/product/B07Y88K754 There are a few things I might change: 1) I'll raise the switch body to reduce tension on the cord. Since it currently points down, I wanted to leave room for putting the back cover on. 2) I'll add a lip inside the hole to help hold the switch in place. In this one, I actually dug small trenches for the clips on the switch. Otherwise, it slips out easily due to little friction holding it.
