Empty Filament Box Storage (4 divider)

This set of 3 slot dividers will convert an empty filament box into 9 equal sections.  The stls fit most filament boxes that are roughly 8"x8".  I have found that a thickness of 1.5mm provides enough rigidity while conserving filament.  

A FreeCad file is provided if you want to make modifications. The .3mf file is for Bambu Studio.

There is also 2 section and 3 section divider models.
