I designed this belt clamp to mount outside of the frame plates on the ShapeOko II so that you can increase the mechanical travel of your machine. My goal is to get a full 12" out of the Oko, but I haven't printed these and installed them yet.

The bottom clamp goes under the M5 screws that mount the extrusion to the end-plate and has slots for M3 nylock nuts. The smaller top cap is designed to use 2 M3 button head screws.
