Filament Spool Holder (Any Length)

thingiverse

I was saving a few extra conduits so I decided to create a filament holder using one of them. The caps are compact enough to fit through the center of the filament spools but large enough to prevent slippage. I secured the caps to the ends of the conduit with hot glue, although any adhesive would work equally well. The actual stands proved to be sturdy, and I fastened it firmly to my table using double-sided adhesive tape. Since this design is easily scalable, I built mine to hold four spools; however, you could easily make one big enough for any number of filaments. To prevent bending or sagging in the center, you can always add another support stand as needed.
