Wind turbine 3D model

Wind turbine model in cross-section with gearbox and generator and rotating blades

I have always been fascinated by wind turbines, their majesty and size as well as their function. Therefore, I prepared a model that would show the structure and function of a wind turbine
I had this model ready a long time ago, but it was simple with a direct engine drive. I improved it on this topic and added a gearbox, cut out a door to the nacelle so that it could be seen how the turbine works.
I wanted to spin the generator through the blades and gearbox to generate energy, but I couldn't find such a motor, so I moved the turbine in the opposite direction through the motor

I did not make the turbine head according to reality, but so that the blades could be turned

I recorded the assembly instructions on video, I will also add pictures with a description of the parts. If anything is unclear, ask me.

Some parts that have a small area need a collar, for example wing, gear axes and blades

To fix the rotation of the Nacelle, use the Tower safety pin, stick it on the tower under the Nacelle
You will need 8 pieces of bearing 21x15x4mm

Power source 5-7V, I used two 18650 3.7V batteries in a box with a switch, but you can also use other
3 pieces of screw M3x20mm for connecting the turbine head
3 pieces of screws M3x6mm for fixing gearbox and generator

4 pieces of screw M3x10mm  for connecting Nacelle A and Nacelle B parts

!!!  I recommend coating the gears of the gearbox with lubricant, for easier movement without friction

Motor N20 6V 60-100 rpm ,I will provide the link

Some parts need to be glued, it's in the instructions
Important! Clean the gears with a brush, they will work better.
This model is more complicated, please be patient, I've tried everything, so it shouldn't be a problem

Update!

Who would like a simpler version of the turbine without a gearbox, only with an engine, I added modified parts. Modified nacelle part, shaft and shaft insert.
Who wants to make tower turbines more easily, you can use the upper and lower tower insert parts and use a commonly used 32mm plastic pipe

Turbine blades used with permission from the Positron author from the model:
