Ender 3 / Ender 5 POM Bearing Spool Holder for 1kg and 2kg spools

prusaprinters

This design takes aspects of @Tony's Longer Original Ender 3 / Ender 5 Spool Holder + Nut, and crandell2's Ender 3 POM V roller Spool Holder on Thingiverse.I love to re-use parts where I can, and POM wheels (or their bearings) are no different. After upgrading to linear rails, I had 13 just sitting in a parts drawer, waiting for a new life. Re-use yours for this design, or buy new ones on Amazon.This POM spool holder is a redesign of the above models, yielding a stock length (9cm) spool holder for 1kg spools, plus a 14cm spool to hold either two 1kg spools at once, or one 2kg spool.Print the spool holder butt end down, with supports. The axle pin can be printed upright, assuming your bed adhesion is good.Use your stock spool nut, or print the included spool nut STL.Included are 1mm and 0.5mm shims in case your print tolerances are off and the spool holder is too loose on your mounting bracket.EDIT: Corrected Amazon URL
