737 Dual Needle Gauge

thingiverse

This is based on the design by Peetvader (https://www.thingiverse.com/thing:3014923). It requires two 9g micro servos with 180° movement. I'm using a full 3d-print while the original design uses a metal nail for holding the upper needle (which is more sturdy but in my opinion not neccessary). My design is intended to be used with a 60x60x3 mm gauge-base-plate and leaves the inner part of the plate mostly free in order to make backlighting simpler.
