Drag Chain Mounting Bracket

One of the first things I made with my printer was a drag chain

Finding a way to mount it was fruitless and I got buy with wire and zip ties ... till I made this part.

This thing is modeled after the common end-switch holders, and clips onto the bottom of an 8mm Z-axis support rod. It's just skinny enough to fit between the rod and the aluminum Z motor coupler

Unfortunately the hot end of the drag chain depends on the extruder mount, which seems
