Fan de Capa para turbina

thingiverse

My printer's top fan uses a turbine without a diffuser, making it extremely hard to keep the temperature stable and causing big problems with extrusion due to the nozzle blockages. I was recommended to add a diffuser for the fan and honestly it has improved greatly. The biggest problem was the height of the diffuser, nothing on thing worked so I built one to size. I'm attaching the file in Rhino so you can modify it as needed.
