I love Pastamatic respooler. The only trouble I had was holding down the spindle ends. I wanted a way to hold the down, inspired by this model. Pastamatic - retrofit for better target spindle retention Remixed by GekoPrime - MakerWorld. You will need 3 copies, plus one if you want to use one on the middle spindle.
12 minutes to print a single, 80 minutes to print 4.
Enjoy
