A simple spool core for rewinding filament onto the bambu spools.
Designed for a tight fit on the spool and easy printing without overhangs.
The start of the filament is alligned with the spool side so you can check how far you have inserted the filament on clear spools.
Not yet tested with the newer white spools.
Made with the personal version of Autodesk Fusion 360 therefore non commercial only.
