CR 10 Z-arm Counter ballance

I made this gadget because after fine-tuning my CR10 the Z axis ran so smoothly that it would keep dropping all the way down to the bed whenever the machine wasn't printing. It also has the benefit of reducing the weight of the cross bar on the stepper motor so it should result in an improvement in quality.

The mod required two brackets, two pulleys two bearings and a weight chamber.

You can alos use the snap-fit bracket for mounting whatever else you require on your printer like LED bars.
