Double rotor addon for wind turbine MK2

Big thanks again to rosch8 for the brilliant original wind turbine! With these parts you can convert the MK2 wind turbine into a double rotor in opposite directions.

The M3 screws for the rotor blades are screwed directly into the spinner. I recommend drilling the holes beforehand with a 2.5 mm drill. I recommend slitting the threaded rod at the back so that you can tighten the nut and hold it against it. 

Required:

1x bearing 608ZZ for rotor

1x threaded rod M8x130 mm for rotor

3x nut M8

6x cylinder head screw M3x16 for rotor blade 

Assembly: 

Install threaded rod M8x130 in MK2 rotor without rear nuts, Distance10, Doppelnabe with bearing and RotorblattR, Distance8, stick or glue ring on KoerperV. nut M8 secure with a drop of CA or alternatively lock a second nut, screws for Koerper.

I printed all the wind turbines with PLA. I recommend brighter PLA up to 35°C air temperature. If it is warmer or if darker filament should be used, then use PETG or better ASA.

I would be happy about a make or remix...
