About this 3D model

I had to make this in multiple parts to be able to print it on my Prusa i3 mk2. A bit of glue might be necessary to secure the arms. I added different sizes of the rod that holds the spool. The length is the middle part where the spool rests. Pick one, or print all. I added support for the dovetail on the arms, but it can be difficult to remove. Adding support in the slicer might be better.
