The file 'Filament Storage – Quick Change 3D Printer Model' is (stl,scad) file type, size is 220.9KB.
This is a combination of two ideas:
Filament Storage Solution (wstein)
Filament Quick Change Roller (Tony_D)
I liked wstein's Ikea box storage solution but the roller wheel system makes it much easier to change one of the spools.
Still not perfect: the rolls tend to "derail" sometimes, especially when the box is not filled completely. I have ordered some 608ZZ ball-bearings online and plan to use 4 of these and two pieces of PVC tube, instead of the small roller wheels. That way, all the spools will roll together, but probably smoother. If it works, I'll post an update!
