Summary

This thing was made with Tinkercad. Edit it online https://www.tinkercad.com/things/bHTzgaeNMWk

This is a simple "Turbine" style Fan blade assembly. It is intended to be driven by a 12V 1A DC motor which has a housing that is usually around 27mm in diameter. This, of course, is not a strict rule, you can drive it with anything you like as long as the drive shaft is approximately 2mm in diameter.

Post-Printing

After printing.....
