2 mm Inner Diameter Piston/Cylinder Assembly

This 2-part model is for making a piston-cylinder assembly using an additional 2 mm diameter metal rod.  The inner diameter of the cylinder is 2.06 mm.  The lower end can receive the 2 mm metal rod in a tie fit.  This setup is for static display models.  The two ends can be fixed using plastic plates cut into triangles to hold down the through holes.  The total length can be adjusted by griding away (e.g., using a rotary tool and a grinding disk) the cylinder into desired length.
