PDF

Designed to be used with 2x 13mm M3 screws and square nuts, or 2x 13mm 3-4N screws and square nuts which can be 3D Printed.

If you choose to use the 3D Printed screw and nut please be aware the strength cannot be a lot so make sure your bowden tube is 6mm.

You will need supports for the clamp ridge but a organic support is all you'd need.
