Quad Coil Holder for 1.25 inch Diameter Motor

This 3D part allows you to place 4 magnet wire coils in position so you can spin a magnet between them using a 1.25 inch diameter motor. 1/4 diameter wooden dowels 1-inch long are used to position plastic Sewing Bobbins with magnet wire wrapped around them. The magnet that spins on the motor shaft should be 1/2 inch in diameter and 1/2 inch long.
The spinning magnet will generate electricity in the coils.

This 3D part was designed using the freeware version of eMachineShop.
