This is a low profile spool holder which can be easily mounted on the top of an Bambu Lab A1. I tried to design it like the spool holder which is shipped with the A1. The PTFE Holder and the spool spindle can be normally screwed on the printed model.

The second Print Profile is inverted for mounting on the left side of the printer.

There is also a model on my profile with the possibility to connect four additional PTFE Tubes to the holder for Dry Boxes.

If you have any suggestions for improvement feel free to write a comment.

Both models are designed for the old spool holder which was shipped with the A1 Printers before 2025. The new style spool holder is not compatible with these models.

This is my first published 3D-Model so feel free to comment suggestions for improvement.
