Bowden Cable Servo Control for Robotics

This is an enclosure for standard size servos to control cables in animatronics / robotics projects.

I'm using a 4mm PTFE tube, the ones commonly used in bowden setups on 3d printers too, and a brake cable for bicycles, fastened to the servo wheel with a part bought in an RC shop.

For the lid to hold the tube tight use an M3 machine screw, a washer and an M3 nut.

For me printing it "the right way up" with supports seem to work best.

I might design a wheel for the servo that can pull the wire around more.

The picture is of an earlier version that was prone to breakage which is now made stronger but I'll leave it there for reference until I take more pictures.
