This is my version of AWTRIX's enclosure
AWTRIX is this awesome ESP8266 based IOT clock with lots of features, better check the related website :
This enclosure uses 8mm magnets to hold on the faceplate.
I provide the schematics for the cutting tool as .DXF file.
This model is designed to be printed as one piece, however, it's a bout 35cm long, so you might want to cut it in half if you printer doesn't have a large enough bed.
Add 8mm Magnets to the enclosure and to the faceplate in order to attach them together.
