3D model description

This is a remix of two objects to make a ball bearing Polymaker spool hub. The thing files are: &

The SCAD ball bearing file was the 5-ball design that I made in a loose and tight fit, the spool hub was the six spoke design with a smaller inner diameter. I combined the two with Tinkercad to make the final object.

The new spool holder fits very well and runs extremely smooth.
