There are two versions of the nacelle:
One for Shimano DH-F703 which has a thinner axle, about 5mm
One for Shimano DH-2N30-E which has a thicker axle, about 9mm
This part adds a slip ring to the turbine to allow the nacelle to rotate indefinitely without the wires tangling. It replaces part "wind_t_h_front_V4.stl"
The turbine tower adapter stl allows you to mount the turntable to the "M10 filleted rod like 50cm" you would have bought for the original design of the turbine.
"turbine apex stl" is an optional additional add on that allows you to mount another threaded rod to the top of "wind_t_h_mid_V4.stl" so you can a cable running from the top of this rod to the end of the turbine's tail, acting as a support cable like on a tower crane.
Does NOT require 2 x bearings inside diameter 10 mm/26 mm outer.
