The file '4-channel Relay Case /w Strain Relief 3D Printer Model' is (stl) file type, size is 452.6KB.
I seem to have a board with smaller dimensions than the original I remixed from. The outer dimensions of my board are 72.3x52mm.
I added a strain relief to prevent the cables from being pulled out of the terminals, seems kinda important to me. That strainRelief Part needs to be printed twice obviously.
Also, I didn't like the holes in the back, so I closed it. Heat dissipation shouldn't be much of an issue, isolation is though. Some other minor changes to improve printability, assembly and self tapping thread size.
