Windmill motorized - N scale

This was made to house a 12 volt motor off of Amazon. The propeller used was from the local hobby shop and can be selected to fit the size you want to make it. Shaft can be replaced with 8mm outside diameter tube in metal or plastic tubing rather than printing the one I made to test. The height can be determined by you, but my preference was to make them smaller than actual height in N scale which would be 3 feet. This was an experiment when I first started with my printer so not exact but it looks good.
