Ender 3 Spool Holder System
thingiverse
Image as reference. I have been using the spool holder by acarita combined with the roller by stauffen https://www.thingiverse.com/thing:4075375 for a while now. This is just my attempt to make it one complete set. I have added a lock nut to the design. Assembly order is shown in the pictures. NUT1 is smaller on two sides so it locks in between the factory ender 3 support arm flanges, creating a strong lock.
