Inspired by llamboladd's Spinning Daisy found on Thingiverse (https://www.thingiverse.com/thing:5229296) I remixed Jozarth's (linked) static prop into a spinning prop. This completes the military aircraft theme of our mixer. 

Shaft and prop were printed in PLA+. The Shaft has an 80% infill for strength. Utilized a brim to ensure it didn't fall over. The hub was printed with PETG, with supports (Larger diameter up) as the mixer has a clamp screw, and finally the prop was printed nose cone up (see photo) in PLA+. The blades were hand painted to reduce print time of multicolor item. Opted to not upload the .3mf profile to allow easier customization by those who download the files.

After all items were completed, some assembly is required. See photo

• As each printer performs differently, test fit the shaft to the propeller, it is a tight fit, sand/file the shaft or prop attachment if needed. On the Anycubic Kobra S1, it popped right into place. 
•  Place the Driveshaft through the hub
•  Glue the propeller to the drive shaft. 

The stickers are available via various on line shopping sites.
