Radian XL Spinner Hub

I designed this spinner hub to accept folding blades with a 8mm root. The blades are fastened to the hub with two M3 machine screws and nuts.

It all fits like a glove with very close tolerances and did not need any post printing finishing of the part or the holes with my printer and settings.

I designed this to accept the spinner cone that came with the model.
