This is an enclosure for sonoff basic switch. i need to open it because of the firmware upgrade so i decided to design and print a custom enclosure. There are 4 sizes for tabs 3,4,5 and 6 mm to secure wire to the case. I provide a led cap in case you do not like the led hole. please note that i developed this enclosure having a sonoff basic r2 power board. it may differ from older ones. for other parts please visit my collection: https://www.thingiverse.com/aRGiRob/collections/my-anet-a8
