Working Steam Engine 3d Printed In Place

Best gadget 3d printed ever ; ) The first in the world working steam engine (pneumatic engine) printed-in-place, no assembly, no support. Just print it! And it works! Get STL model at: Engine works from mouth blow! I worked hard to design this engine, printing more than 100 engines and optimizing them one by one. Simple but effective. Power and beauty. 14 secrets of technology JUST PRINT IT ! Despite running on compressed air (from mouth breathing), this type of engine is called a “classical steam engine“ due to its construction (valve linear scheme = 2 in 2 out). Only a few (!) people in the world can make an engine powered by breath. It is very difficult to make such easy turning engine. And no one (!) on this planet has ever made a working engine printed entirely on a 3D printer without the need for assembly ; )
