Is there going to be any further development on this?

im going to print this with PLA, I am not going to use the gramophone motor as i dont have one, have plenty of other types, I might even try a very small 12 volt motor, I think its rated for 3000 rpm, sooo it will be interesting what voltage i will get.. Id be happy with 2.5 volts with small current to power a few LED'S, But ill see if i can get it to spin first once printed :)

The tip on your blades is part of your vibrations issues and if you narrow it considerably you will probably get more RPMs which means more electricity.

I must print one of these. I need to find a source for a DC Gramophone motor. What would you suggest as alternative?

Incredible code. Thought of offering classes on openscad?
