MPCNC Wire Harness Washer-pair

This is a replacement for the pair of fender washer that go on the [Mostly Printed CNC (MPCNC) version 525](http://www.thingiverse.com/thing:724999). It provides zip tie anchor points for wires (or a flex tube containing wires), corner anchor points for the wires going to the motor, and a channel for wires going into the conduit across to the other side.

This object gets printed four times and affixed to each roller on the MPCNC and allows simple routing of cable without any danger of cables getting snagged in the pulley mechanism.
