I added in No Support Spool Holder which is now my recommended print. Generated support has come a long way and this now prints better that way. I also added a little reinforcement to keep the piece from breaking when in use. Still recommend 75%-100% infillV5 minor modifications to improve printing. Reinforced legs on the ToyBuilder and Makerbot holders so they are less likely to break if you push on them too hard.V4 Added a ToybuilderLabs holder. Technically the Makerbot one will work but it's next to impossible to get it through the hollow center of the spool.V3 Added a 10mm shorter Octave spool holderReinforced the walls of the Universal mount.Highly recommend 100% infill for structural strengthAdded the Inventor Project FileV2 extended the makerbot version so that it fits the larger spools.Octave spool holder more flexible and rounded for better printing.This is a spool holder that replaces the one that came with the 2X.The "holder" is a univeral fit and can accept any type of Spool core.Currently Makerbot and Octave are supported.
