MPCNC Drag Chain System

Update: I've modified this design to work with the Burly build, either attached to a new XYZ piece, or clamped on like this design. https://www.thingiverse.com/thing:4032440

I really enjoy using my MPCNC, but I've always been a bit uncomfortable about wire harness management. In particular, getting power and control to the gantry in a "clean" manner that also did not require any attachment to the gantry itself for best precision was the major problem.

Taking a cue from another user, I designed a carrier for the drag chain that clamps to the side of the XY piece along with a track using 3/4" aluminum angle and two servo mounts. I used the very good drag chain attachments from https://www.thingiverse.com/thing:1272581 to complete the routing of all the wires. I chose a clamp attachment method to avoid having to reprint and disassemble/reassemble the entire center piece of the CNC.

The center mount attaches with a clamp screw from either end of the side piece using a nut
