Soft Tape Spool - Ball Bearing Edition

This is an enclosed spool for a 13mm (0.5inch) wide and 150cm (60inch) long soft tape that uses a 22mm ball bearing for smooth rotation. I encourage you to modify this model to fit your own soft tape and ball bearings. If there is interest, a parametric version can be made to accommodate this more easily.

 

Both 3MF and STEP files are included.
