The drive horns go through both sides of the gearbox.
The potentiometer is mounted to the gearbox indirectly using an involute gear.
UPDATE: Use the -1 files. They are newer and make screwing the gearbox together easier.
All parts can be printed at 0.3mm EXCEPT the gearboxscrew.stl
slice gearboxscrew.stl at 0.2mm or less. Print very slowly with a fan as this has lots of steep angles
You will need to take the servo apart and modify it to allow continuous rotation
All parts should go togther as per the exploded diagram.
Once assembled, push the potentiometer through the hole in part "bottom plate pot holder"
attach with a screw
