Drag Chain Mounts for MP3DPV4

Modeled for the MP3DPv4 , this mounts over the end of one of the Z stepper motors and holds the 10mm square drag chain that I have. This is characterised by a 6mm attachment bump and interior spacing 14mm on the outside diameter.

There is also a mirrored version. I intended the drag chain to mount facing downwards at the motor to exit at the extrusion facing upwards, as this made the most sense for my wire management. (Somehow, I ended up drawing it upside-down though.) I suppose it could be reversed, but the clamp bolt could be a problem clearing the heated print bed. The mirrored part would allow you to try, but is meant for the mirrored Z mount.

From the center of the motor to the center of the drag chain is 59mm, which is what I measured from the Fusion360 model of the MP3DPv4 going to the centerline of the extrusion. This should allow excellent alignment of the drag chain to the extrusion anchor.

In order to attach this, I recommend an 8-10mm M3 screw and nut to clamp to the Z motor, and up to an M5 screw and either a hammer nut or a sliding nut for the extrusion.
