This is a turbine designed by Nikola Tesla. it is said to have a 95% efficiency rate and I have modified it. I plan to plasti dip the part to make it air tight. Compressed air needs to flow through one of the two hole at the top with a 1/8" Rod going through both exhaust plates and the spindle (Yet to pictured) Pleas use the proper safety equipment during use. I am not responsible for any injuries during the use of this device.Print two face plates 1 body 1 spindle Wear goggles and take other necessary precautions Please print the spindle with one of the flat sides down and of course the body with the large face down.
