tailshaft plug

This is based on a tailshaft plug commercially available through snap on. It is somewhat universal. this and the other one are supposed to be one piece, just on opposite ends, but i saw no reason it couldnt be 2 pieces for ease of printing.

50%infill and PETg recommended due to it being where oil is.
