Wombot Filament Spool Locking Inserts
These Filament Spool Locking Inserts are designed to work with the standard filament spool rod included with the Wombot. Simply slip one over the rod, slide your spool onto it and push it over the bump on the insert, and the force on the bump locks it on to the shaft. Then tap the other insert in on the other side, and your spool will be held securely to the shaft, permitting the shaft itself to spin inside of bearings, or whatever you decide to use.
One size is for the Aurarum filament spool ID, the other is for 54mm ID spools. I will make more sizes and add them in here as I discover more spools with different IDs.
