Universal Filament Spool Hub (Uholder1.stl and Uholder2.stl ) is designed to reduce friction of the spool rotation. Excessive friction can lower the quality of the print. The hub can be kept with a spool during the storage. No need to remove the hub after and put it back before the print. Keep the hub on a spool all the time.

There were following design priorities:

- minimal friction;
- accommodate variety of spool widths and hole diameters;
- hub shouldn't extend the width of the spool
