Hex bore encoder for AM 57 sport

This is the latest version of our hex bore encoder housing. This one mounts on an Andymark 57 sport gearbox, but still uses the internals of a Vex versaplanetary encoder. Used on our 2018 robots. *Note* don't forget to lubricate the internals with (non conductive) grease, and avoid putting axial loads on the housing. PLA deforms at low temperature, so keeping friction down is a must.
