Printing a prototype propeller for my Lightnin lab mixer

Friday 8th September 2017

The worn-out stainless propeller was going to cost $500 to replace. But the size and pitch of the blades was not ideal anyway. So I drew them using insight-live.com/picture/2453">Fusion 360 and printed in PLA plastic, this enabled experimenting with different sizes and pitches. How about getting a tight fit on the shaft? No problem. I measured it with calipers and printed that size. It was a little tight so I printed it slightly larger. One issue: Mixing slurries with hot water bends the blades and the collar loosens. If you would like this in Fusion 360 format, it is available in the Files Manager in your Insight-live.com account.
