Very simple fan wind tunnel to test the fans wind speed with an General DAF3008 Anemometer.
I understand this might not work for everyone (many different Anemometers out there). So i attached a step file if anyone wants to change it.
I don't expect many people to print this, but i decided to at least share my results incase it would be useful to anyone.
You should not need supports for the file. Definitely print it with a brim and at the orientation below. The holes in the model are 3mm, to fasten the fan just use some M3 bolts and they will tap their way through:
