Ender 3 Spool Holder with Bearings

thingiverse

A simple holder for the Ender 3 stock metal bracket uses two bearings to facilitate easier spool rolling. The design harmonizes perfectly with the default printer, mitigating the sharp angle between the spool and extruder assembly. A removable cap is conveniently included. The flat bottom ensures secure platform adherence. With 100% infill, a total print time of approximately 8-9 hours is required for both pieces. M4 screws can be used to securely hold the bearings in place, with pre-drilled holes featuring threaded models. Note that this design can be modified to feature one continuous taper on the bearing holder, eliminating the need for screws to secure it.
