We had the Fantic Motor Minarelli fan remade for us. It is injected molded, and much much stronger than the cast, or 3d printed fans running around out there. It is slightly higher taller than other 108 fans, but you can sand down the edges to get it to drop down where you need it.
Check to see which version you need. It will be either the 103, or the 108. More versions are in the works!
