SpoolBoy

I needed a compact spool holder for my Mosaic Palette+ as using the box it came in is messy, takes a lot of space, does not place the spools in the best position for the Palette+, and is almost impossible to access once the print has started.

This design accomplishes the following:

1) Holds up to four spools of filament in the smallest foot print possible.
2) Organizes and positions the filament for best use for the Palette+.
3) Accommodates full size 75mm x 200mm diameter and smaller as well as smaller-holed 90mm x 160mm diameter old-style Robo 3D spools.
4) Allows easy access to individual spools of filament even while it's printing.
5) Makes it easier to move the holder plus all the filament around.

The shafts are long and slim for use with old style 90mm Robo 3D filament, but I included shorter shafts for 70mm and 75mm sized spools.
