80mm fan experiment
Description
A little experiment to find new turbine with better performance. Sadly I have nothing to measure airflow in any values. But I found out that balancing test piece on an air using knife edge may give comparable results. So the winner is:........... ta-da-dam v3 version (Radial blower one) - see update below P.S. v6 is original (60mm fan), which after cutting top solid surface became v5 UPDATE: printed 2 more fans and we have a new winner. My measuring piece have reached its limit, so I moved to wooden ruler. So the best version on 04.2020 is v8 = turbine-forward-v2 by cimo v7 by DrRalph (modified) is better than v3 on old test piece, but bit worse on wooden. And v7 has most finest rotation without virbrations.
