Arduino Dual-Relay Box

thingiverse

This is a compact box fitting an Arduino Nano and a dual relay module. The box is easy to print and can be assembled without any screws. If necessary you can use two zip ties in the slots on the front and back to firmly close the box.I have decided to include sufficient space to mount an Arduino Nano including mounted pin headers. A slightly more compact design would be possible without the pin headers.Relay modules which fit the regular size:2-channel relay module, black PCBRelay modules which fit the "wide" size:2-channel relay moduleI can of course not give any warranty that your module will fit but the design is adjustable at least to some extents by moving the module clamps.The Arduino Nano PCB will fit into the molded slot and being held in place by slots in the base and within the lid.
