Filament stack with free spinning spools

This deign combines filament storage with dispensing. Shown here is a (4) color tower, but I think 6 to 8 color towers would work as well. This should be easy to grab from the top and move to your work area.

Marbles are used as ball bearings. They are quite effective, the spools spin very freely.

I used PVC tubing in this make. And the top and bottom pieces are ply as my printer is very small. The top and bottom stl's are included. Future versions or add on's might include vertical pieces
