idler arm: extended the idler arm to now be able to disengage the gears and unload filament by hand
front: modified how the threaded insert is held in place
(because sketchup is rather messy and I'm no pro in using it, the stl mesh is broken and the “fixed” mesh won't be 100% clean)
The author remixed this model.
- extra length added to the idler arm
- modified how the threaded insert is held in place
