The file 'Replacement Bathroom Fan Impeller (3/16″ Diameter Shaft) 3D Printer Model' is (step,stl) file type, size is 66.6KB.
Replacement impeller for common bathroom fan systems like Broan-NuTone. Been using this in my bathroom and it works fantastically.
Fits on a 3/16" diameter shaft (with a .25mm tolerance). If it doesn't fit, you can always cram some glue in there or edit the STEP file and change it to better fit the tolerances of your machine.
