Universal filament enclosure - spool locking shaft with ball bearings

thingiverse

Filament enclosure spool locking shaft features ball bearings for smooth operation. The 300 x 300 print bed accommodates large prints with ease. A new version of the design replaces printed bearings with standard ball bearings (600042RS, 204212) to ensure reliable performance. A printed bush/bearing STL file is included as an optional alternative. Important: Ensure you upload the latest version before printing, as some parts have been modified since the first update. The design includes two external circlips for securing the bearings in place. To assemble, mount the lower bearing on the Base-Shaft and secure it with one circlip. Next, attach the Shaft (bearing house) and finally, install the Upper Bearing, securing it with the second circlip. Note: This design has not been thoroughly tested.
