spool adapter

thingiverse

A simple adapter is created to fit the larger (55mm) hole spools snugly onto the Ender 3 spool holder, ensuring a smoother feeding process when the feeder pulls on the filament. Two adapters are required, one for the front side of the spool and another for the back side. This setup provides more versatility since not all spools have the same width. This adapter is designed to make a big difference in your 3D printing experience!
