Excellent, once the parts were cleaned up everything fit nicely together. Although some parts had to be persuaded by a vice.


Deviations from specification of the designer: * No nylon parts, all parts are ABS * 0.2mm pitch used instead of 0.1mm * Unit shown in picture does not have O-rings, springs, or ball bearing. Will purchase those soon.
