TH3D Spacer Camera Arm Replacement Mount

While upgrading my CR-10S with some new parts from the fine folks at TH3D, I managed to break the mounting pins on the camera arm attached to the solid bed mount I use. Rather than order a replacement, I came up with something a little bit better - a cap that fits over the end of the camera mount with sturdier mounting points. Just print with 3mm walls and supports on, pour some glue into the cup, put the cup on the arm, and in about five minutes you're good to go.

This is designed to fit an M3-sized machine screw and nut.
