Free 3D Printer Parts STL Download - Ender 3 Spool Upgradeby RG3D Prints

Cardboard spools don't spin very well on the stock ender 3 spool holder. The additional tension was causing my TPU to slightly under extrude. To fix this I made this, it uses standard airsoft BB's and can adapt to many spool widths the way I made it. Print the 2 different tubes and 2 of the end pieces, throw in your BB's and it will slide right over the stock peg.Its been working great on lightning infill with 4 walls. Don't really need more than that. Files should be orientated properly for printing and no supports should be necessary.
