Qidi-Tech X-Plus Interior Spool Holder

A spool holder to replace the current inner spool holder. Fits two standard bearings for the spool to rotate on super smoothly.
I used Autodesk Inventor's Degenerative modeling to create the shape from a hollow tube to make it look cool.

Here is the picture of it mounted inside the printer with the bearings:

Printing:

Disable coasting to print thin sections better if using PETG which has a better bond strength between layers.

Print with no supports or block supports in the outer wall. The only place it is helpful is along the bearing shaft.
