Filament spool that fits inside the FABtotum fabricator.
v003: Be aware that this model is the exact thickness of the available space inside the FABtotum (with the side panel closed). It works fine on my printer, but might create more than friction than necessary.
v004: Is 2mm thinner than v003 and has a center hub with a 8mm hole to make the process of adding the filament easier.
Print the piece twice, then glue together. I used a 3Doodler to do this, but a regular glue gun should do nicely as well.
