Ultimaker filament spool
thingiverse
Since I'm creating a PET pultrusion machine with an Ultimaker filament spool, I created a model of the actual spool for sizing the mechanisms and holders of my machine. The model is close to be quite accurate since the original spool has been designed for injection molding. I'm sharing the .stl file plus a .step file for easier use.
