A small spool designed in Tinkercad.
I had a bunch of loose filaments that came with a 3D pen and I needed a temporary spool for them during printing to prevent tangling. There are quite a lot of these but I just had to make one of my own. :)
Outer diameter is 10cm and the inner diameter (hole) is 4cm.. should fit all printers..
The small holes for the filament are for 1.75mm filaments.. use an exacto knife or screwdriver to widen it if needed..
Print twice and attach together.. should hold fine.. add a drop of quick glue if it doesn't..
No supports needed..
