This is a way to mount the mgn9 rails to a carbon fiber tube for use on a 400mm Ratrig V-core gantry. Print this 2 times for the whole length of a 400mm X-axis gantry. Insert both bottom and top piece with M3 flange nuts in position. Fasten all the screws, remove the bottom piece and leverage the jig out.
Use bottom piece from the original creator
