Here are some redesigned X-Carve drag chain mounts for a 15mm x 20mm drag chain on the 1000mm X-Carve. I did my best to increase the rigidity of these parts.

HARDWARE: You can get the hardware at lowes or homedepot for about $5. You'll need: UPDATE: Part 14058 works but i think it could use more rigidity, feel free to modify my design and beef it up (maybe draw inspiration from an I-Beam) or print in Nylon. Printed with a .8mm nozzle at .6mm layer height in ABS. All the parts took a total of about 2.5 hrs to print. I recommend installing the drag chain mounts prior to mounting to the x-carve. If you have clearance issues use a needle nose pliers as your reaction tool.
