#UP Temp control box, for 12 position rotary dial

This box sits on top of the UP, ribbon and hothead plug PCB, and allows you to add a 12 position rotary dial with 1.8 ohm (5 deg) temp drops to each of the 11 positions, 1 being FULL temp.

I have not done the mod or test printed this box, so it may still need a little adjustment.
