Bambu Lab spools winder SIMPLIFIED !

Hi, I needed to bring some filament onto AMS compatible spools, I've seen excellent projects around but too complex and expensive, I don't want to waste filament, time and money buying bearings, screws or anything else.Simplifying as much as possible and without needing anything else apart from a printer, I designed this. Simplicity is fundamental for me! you can use the crank, or a screwdriver on the removable pin.WARNING: for the unwinding spool I use an open filament dryer, otherwise
