2 different propellers, clockwise and counterclockwise.
First glue the propeller to the stick.
Stick is made for cordless screwdrivers with 7 mm drill chuck. Rotation propeller has a diameter of 50 mm, so the edge and the inside of the paint can must be more than 50 mm wide. Total height of the stick with propeller is 142 mm.
If you have smaller paint cans, scale down the stick and propeller before printing.
