Ender 3 Pro Spool Bushing
Description
This spool bushing is used to guide the filament spool on the stock Ender 3 Pro spool holder (no modifications required). It allows a clean and concentric rotation of the spool during printing. The bushing is held in place using 2 inserts that allow it to be mounted radially and stay firmly on the stock holder. The spool is tightened on the bushing with an ergonomic and easy to use nut. An additional bushing sleeve can be printed to accomodate virtually any filament spool's internal diameter for ease of mounting. The external diameter of the bushing is Ø52mm. Some lubrification can be added to minimize the friction between the stock holder shaft and the bushing.
