Was browsing through a sea of endless overcomplicated spool holders and adapters. Decided that there had to be a better way! Here is my take.
Super fast print and the only hardware you need is two zip ties and two 6x12x4mm bearings (MF126). I got mine from my Traxxas RC car parts bin. You can get some on Amazon here: https://amzn.to/2zqP9rN
UPDATE: Added files for 5x11x4mm bearings (MR115ZZ). You can grab a set here: https://amzn.to/2Qloh21
Simple, and adjustable.
Enjoy and post your makes!
