MakerGear M2 Universal (Left or Right) Spool Holder

thingiverse

I'm transforming my MakerGear M2 into a twin extruder setup based on Tim Edwards' design documented here: http://opencircuitdesign.com/~tim/3d_printer/twin_project.html One of the first modifications I needed was an additional spool holder for the right side of the machine. MakerGear's spool holder from GitHub is too large in diameter to accommodate 1-1/4" spindle hole spools like Hatchbox. It also extends 4-1/2" and is too long for my needs. I located a different spool holder that matches the correct diameter, but unfortunately it's even longer at about 5". This spool holder starts with the same dimensions as MakerGear's factory left-side spool holder, which measures only 3" in length. It has a standard diameter and comes equipped with (4) mounting holes on the left side and two additional sets for flexible installation on either the right or left side at different heights. So far it works smoothly without issues.
