Description
Generating electricity with the DC motor of an old gramophone and
a printed windmill.
The first tests gives 2.5 V and lots
of vibrations of the windmill.
later more..

Instructions
Print:
1 xBaseInOnePiece.stl
(or when the piece is too big
1x baseFront (for the front M4 bearing),
1x baseMid (for the back M4 bearing),
1x baseBackPart(for the generator and
M10 basebearing)
1x BaseBearingHolder.stl (to connect the base axis via the base bearing
to the base)
1x TailPart
3x windMillBlade
1x hub
I added an extra plane to the windmillblade to get a
better print quality, after printing the extra plane can be removed with a saw.
Put the stuff together with:
1 x DC motor gramophone
2 x threaded rod 500mm x M5
12 x nut M5
12 x ring M5
1 x threaded rod 200mm x M4
2 x bearing M4
4 x bolt M4 x 40
6 x nut M4
4 x ring M4
1 x threaded rod x M10
3 x nut M10
2 x ring M10
1 x bearing M10
1 xBaseInOnePiece.stl

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?
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 :)
