RatRig Vcore-3 MGN9 carbon gantry

Here is my design for mounting a carbon square tube and MGN9H rails on RatRig Vcore-3.

This also solves some issues while tightening XY joiner plates and pulleys/idlers alignement.

Note1: New XY joiners can be used on it’s own with original 2020 aluminium extrusion but you still need shoulder screws.

Note2: Original MGN12 linear rail can be retained if you are not looking for big weight reduction. Simply drill carbon tube accordingly

[20220313] Added reinforced X_endstop that come flush with XY left joiner (only for use with MGN9).
[20220624] Increase tolerancy on Carbon tube insert for better fitting with nylstop nuts

XY joiners rev1.1: aesthetic change plus weight reduction
