This potato gun is designed for fun. This paper presents the build itself along with .stl files.Since this gun is made by 3D printing.The materials used are ABS or PLA plastic. The principle of operation is that through the needle valve(when opening the compass, it will be called the second and one part of the valve), the oxidizer and gaseous fuel are fed.Submission is carried out separately.After that, the fuel is ignited with a fuel burner. Which is installed with a tight fit in the cover with a hole under 10.25 mm (part name "gun cover"). Needle valve-consists of two parts,where a needle(0,8*40,5), a spring(3*24) and two locking washers are installed.("Tight fit washer with needle") moves along with the needle ,which in turn presses on the spring while feeding the main components for the gun to work.("Free-running needle washer")it is installed in the groove, where it keeps the spring from transverse movement, and also allows the needle to move.Since this is a gun and it generally has to shoot something,then it needs projectiles.There will be no specific requirements for this.And as mentioned above, this gun is for fun and ceremonies should not harm the health of others.
