FIBERLOGY MasterSpool

A simple tool that allows you to reuse old FIBERLOGY filament spools.
Now you can put refill filament on the spool that you already have.

All you need is to do one cut to separate the spool and place inside printed elements. In most cases, the finished product does not require additional gluing - the elements just pop up.

UPDATE :) !!!

Master_A_V2.stl with greater thread tolerance. Only smaller part has been changed, so you can use first version of Master_B with updated Master_A_V2.
I hope after this update everything will work smoothly and there will be no need to adjust the model.

Please do not hesitate to give me feedback - I will take all your comments under consideration.
