Wind Energy Stored In Gravity

I've included full models of the turbine and fan along with sliced versions for simpler printing. You can easily reduce the number of fan blades, flip them around, or attach a motor/any other feature you prefer. I suggest printing in ABS with a .2 layer height and 30% fill. The rack gears serve as the battery weight, so it makes sense to print them at 100% fill, and/or add additional weight to the gear to increase torque. Let me know if you have any questions!
