Upcycle Empty Filament Cardboards

I was tired of throwing away empty filament boxes.

This design transforms your used filament cardboard into something actually useful.

Simply cut your filament box along the folding and slide the pieces into the 3D-printed frame - no glue, no screws.

The result: a clean, sturdy storage box that looks great on any maker’s desk or shelf.

I am curious what you think about it!
