USB Relay Box
prusaprinters
I printed it with 3 walls with 15% infill. You need 4x 10mm M3 bolts for receptacles, 2x 30mm M3 bolts for cover, and 6x M3 nylock nuts.My relay module has, a USB-B connector and it is labeled as HW-348. I made some tolerance for the PCB because they are not consistent with dimensions.I bought some generic IEC receptacles, hopefully they are standard.I encourage You to put some 10A (or even 6A) fuse inside as your electric circuit is probably rated to 16A (most of Europe I think?), but relay and receptacles are rated to 10A.
