Summary

Easy access filament drive for the Makergear M2 with a V4 hotend. I have incorporated a rotating nut that will allow you to rotate the machine screw out of the way in order to make it easy to remove the bearing section in order to access the filament.

This version has two slots for Machine screws in order to give a more even tension the filament idler bearing.

This is a Remix/Combination of the original Makergear V4 Filament Drive, incorporating the bottom latch part of Narosenberg's Easy access design.

Post-Printing

To make the pivoting nut, I cut the non threaded part of a fairly long 1/4" Carriage bolt, and drilled and tapped it to accept two M3x0.5 socket head hex machine screw. The machine screw will need to be ~ 25mm in length. (I cut down longer ones to fit)

Be sure not to use a Grade 8 Bolt, as they are quite difficult to drill & Tap (I broke off my tap trying to thread one)
