This is a Filament Spool Holder that I designed for myself since I lost my original one during my last move. It is almost entirely 3D printable, aside from the 3 necessary 2208 skateboard bearings.
The 3D printed threaded rod should be printed with pretty high infill and at least 3 perimeter wall thickness.

There is a test print file for the threaded rod, and it is important to test out how well the knobs rotate on the threaded rod.
