This is an Eolic machine that can be use to move puppets or other things.
I've done a reduction only to the half of the speed, but i'm figure out to make another support to fit with a 30 teeth gear to increase the reduction factor.

In the model you see in the pictures i've sized the propellers only to the 60% of size and it seems to be enough. **N.B. If you scale the propeller and rotor like i did, pay attention to the rotor_base.stl screw hole: it will be scaled too.**

I've used these ball bearings for propeller and z axis movements: https://www.amazon.it/gp/product/B019Z8UZNY/ref=oh_aui_detailpage_o01_s00?ie=UTF8&psc=1
I've made all support to fit these type of bearings but you can use your own and redesign some supports.
