Needed to surface mount my new Siemens FS100 whole home surge protector. The kit from the manufacturer was $100+ for a piece of metal and some hardware. Took measurements and created this print. Since I could not print in one piece, it is designed with 3mm holes in it. I ordered 2.5mm x 100mm steel rods that fit into the holes. When it is all assembled, this provides structural rigidity. I also used an M4 nut/washer kit along with 75mm sleeve coupling nuts to mount the surge protector to this. Picture shows all of the parts needed.
