Drag Chain Mounts - Inventables X-Carve

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.

DRAG CHAIN:
The drag chains I sourced can be found on Amazon but the ones from eBay should work too:

**You'll need to order 3 to get the full range of your x-carve by snapping a few more links on each chain.

HARDWARE:
You can get the hardware at lowes or homedepot for about $5.
You'll need:

• 8x M4 x 12mm (countersunk)
• 4x M4 x 12mm (button head)
• 10x M4 nylon lock nuts or plain hex nuts (easier installation, but may become loose over time)
• M4 washers (optional)
• 2x M5 x 8mm (button head) (but i used M5 x 10mm with washers)

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.
