This is a Filament storage solution that I spent many hours and spools developing. It takes some inspiration from other designs, specifically Racks4All by Jorge Rui, but is mostly original besides the form. It is well refined and should work well for all storage needs. If you are cheap and don't want to spend too much on filament you can lower the thickness of the walls to make it cost less filament at the expense of some rigidity and looks. If you want it to look a little bit better as well as make it very strong you can reset the slicer settings back to normal. This design took me longer than expected and it is my first post.
