MP Select Mini External Heatbed Wire Mod

Many users have this timing belt grinding problem with this Monoprice Select Mini 3D Printer.

The wires for the bed heating are routed underneath the print bed. During movement these wires will grind against the timing belt and may cause prints to fail.

In this video I will explain how to reroute the wires to be external and also install new metal pulleys.
