Box for CL4-GSM mobile phone remote relay

thingiverse

This is a box for a 4-way gsm remote relay to control a electric socket via SMS. Don't mess about with high voltage if you don't know what you are doing. It is very dangerous, you could get electrocuted or start a fire! I find it difficult to print this in ABS as it warps. I used PLA in 0.45mm layers and a 0.5mm nozzel. Use M3 nuts and helicoil inserts to assemble and a M6 eye bolt and lock nuts for a hook. Small wood screws instead of M3 may also work. But be careful that the lid is not ripped of as connectors are pulled out. Use a plexiglass piece as window to see the status leds, or print a blind if you don't need it. Leaving it open may cause small animals and bugs to nest inside the box and cause fires. Use a M16 cable tension relief on the cable and a 10A glass fuse in a 12mm fuse holder to protect the relay.
