Old Style Windmill

This design is inspired by old windmills that were used to ground wheat into flour. I always thought they looked quite scenic and was surprised when I couldn't find one on thingiverse.

This was designed in Autodesk Inventor. I went through several iterations trying to find a good gear ratio until I realized two of the same sized gears would obviously mesh well. The pictures and video only show the top two layers and a different gear ratio.

Here are some videos:

As you can see, the gears don't mesh perfectly so there is some friction. Once the top is removed however, it spins quite fast. The model I uploaded shouldn't have this problem.
