Filament Spool Storage

(Work in progress)-I was looking a filament storage solution that would work for my needs. Didn't find any that fit so I made this version. It's a work in progress and I will update asap. This is a simple print and stack system. This should fits most filament spool sizes, and let's the spool overhang about 15-20mm to allow you to grab the spool. Update- I have included the first version with solid top and bottom (V1) and have adjusted the connecting parts for a better fit (.2 versions). Testing ongoing.
