About this 3D model

Note, this spool holder axle is designed for a spool with a central hole diameter of 53mm. If you have a spool with a different diameter, you will need to add a suitable adapter ring for it to work. Referencing the AMS axle structure, this axle kit (diameter 53mm) is custom-made for the A1 machine's filament holder, and includes an adapter for modifying the feed opening height. Printed in PLA by default, no support needed. For detailed installation instructions, please refer to the images on this page. Pay attention to the installation direction of the washer. On the side of the filament holder, you can see a screw. Unscrew it, and you can detach the holder and install it on this adapter. A screw hole is reserved on the adapter, which can be secured with an M3*12 self-tapping screw, or you can choose to install it without a screw.
