Hacked Servo Pot Frame with Rack and Pinion for Linear Feedback

Hack a servo for continuous rotation (remove the pin on the main gear, and rewire the pot so it is outside the servo)
Install the gear into the frame. Install the rack gear into the frame. It snaps into place with the hole side of the gear facing the outside of the frame. Install the potentiometer into the frame and lock it in place with the clip. You can see the clip in Thingview...
Be mindful of what position the pot is in relative to the travel of the rack gear. Set properly you should get about 50mm of linear travel.

Print with support 2.5mm (mainly for the pot cavity on the main frame)
You only need to print 1 gear. It's a remix of Gael Langevin's InMoov elbow gear, but scaled up 9.5% (Scale 109.5)
