Reprap power supply terminal cover
by Wired1, published
Name says it all really, these power supplies are perfect for reprap printers but they do have horribly exposed live terminals giving you a nasty little surprise when your fingers slip while adjusting the output voltage.
The cover mounts using the existing slots in the front of the power supply and neatly covers the terminals yet still give you access to the adjuster trim pot as well as the friendly green "on" LED.
Print it out and mount it with 2 of M3 x 8mm machine screws and nuts or equivalent.
Recommend printing it at 100% infill as it is only 2mm thick.
Added version 2 with "LIVE WIRES" text added.
