This model was originally developed for my personal use, but I decided to share it here. I hope it will be useful to someone else as well!

This model is a two-piece sewing thread spool. I use it to rewind thread from larger spools, and it is very convenient.
Example:

In the print profile, I selected the most suitable settings through trial and error to achieve good and consistent print quality with a minimal seam that is almost invisible.

If you have any suggestions or ideas for improving this model, please feel free to share them. I’ll be happy to help!
