The model is parametric in fusion. The model is quite large and won't fit most printers, so either scale it down or edit the parameters. 

Important: The fusion model is split into to parts, because fusion doesn't allow to join both parts. When you export it as 3mf you'll see two parts. Select both of them and press assembly in orca slicer (similar in Bambu studio). This will join the parts correctly. Generating an STL of the whole file also worked for me.
