Arduino Nano AC Power Control Box

thingiverse

I built this enclosure to house an Arduino Nano, which utilizes a thermistor to help determine when my 3D printer has finished a print and power it down. I've included some of the models I put together, for purposes of sizing during my design process. The design includes placements for 2 push button switches, plus a photocell. With the use of a 4 relay module, the outlets can be broken up into 4 separately controlled outlets.
