Having bought a 30A power supply for my Makerfarm Prusa i3, I was concerned that the terminals were all too readily accessible. I decided to make this cover to provide a good degree of protection for the live terminals while adding a DP switched inlet for the mains. The PSU in question measures 215mm x 115mm x 50mm. The terminals sit on a 'plinth' along the lower front edge. If you've got one, you'll know what I mean. This is my first design and bespoke 3D print, so I was relieved that it worked as well as it did. Enjoy!
