lovejoy coupler 3mm and .093 inch shafts

this is a 10mm diameter love joy type coupler, for a small motor with a .093 inch shaft to couple to a generator with a 3mm shaft. for a roto verter project of mine. i gave you the blender file so you can make what ever shaft diameter you want. i will press the shaft on, because the speed of the motor will make a bolt be an off balance and blow apart
