Filament Spool Winder

I modified the coil holder, which is completely printed in the original, for the threaded rod M10 and M8 (120 mm long). Why M10? Because the piece was rolling around in my drawer :-D The version for M8 is more logical, since the author designed the model for rods with a diameter of 8 mm. I am attaching a file from FreeCAD and stl files with prototypes for possible further modifications. I thank the author of the model for a nice and functional design. It serves me not only as a filament winder, but also as a demonstration of how to design mechanically functional models.
