A DIN rail mount extension for the sonoff THR20D or POW elite 20A.
Units come with a DIN mount but they are recessed when inside a DB and takes 3.5 din slots.
This design brings the screen to the front and allows the units to take only 3 slots.
It has some compliance built into it since the front panel distance to the rail of DB's may vary.
This print is mountable with a strip of double sided tape, glue or four 12x4mm machine screws. They thread poorly into the back of the sonoff screw holes.
