Stackable Filament Shelf / Holder

A stackable shelf for boxes or spools of filament. Designed to fit most filament boxes (have tested with Bambu and Polymaker since that's what I keep on-hand). It has a little holder on the side where you can break off a small section of filament (a couple inches) and slide it in on the side so you know what is in the box without having to pull it and open it.
