Spool Holder

Holder One is a fully functional, printable “AMS lite Rotary Spool Holder” that can grip not only bigger internal diameter spools (up to 75 mm vs. 58mm) but also smaller internal diameters (as little as 33mm vs. 53mm). It also includes a safety lock that stops the device from detaching and falling from the AMS or A1 mini.During the printing process, the printer feeder unit pulls filament from the spool. Holder One works in coordination with the printer feeder to enable the spool to rotate continuously, ensuring that the filament is fed with constant adequate tension. This prevents spool erratic rotation, which can result in filament tangling. At the end of a print or when there is a filament color change, and the printer feeds the filament back to the spool, Holder One will rotate back up to 180 degrees, maintaining constant filament tension. This prevents the filament from unwinding outside of the spool, which can cause a jam.Version 2: I have modified the clutch element to include ad
