Cylinder Assembly

Cylinder assembly for my first project in Mechanical Drafting and Design class. All dimensions and features are in metric apart from the 1/8" NPT ports. Calculations were done on the buckling of the piston rod and chamfer sizes for seal and seal gland compression. Travel is 15 mm. There is a limit mate in the assembly so it will only travel to either cylinder head. A few configurations are included (exploded view and those shown in screenshots).
