This is a 3D Printable Scale Model for the Soviet Double AA Gun of 37mm. The model is divided in all its basic parts for resin print; 23 Files containning the individual gun and carriage parts. Some parts are gonna be necessary to be printed multiple times, but it is very intuitive; canions, wheels, carriage suspension.It may be overwhelming seing that ammount of parts, that why the model files are arranged on 2 different groups while also being numbered. The files contain the parts for the Gun itself and the ZU-7 Gun Carriage for display. Both models were designed to be assemble on different positions; wheels can rotate and change it's height, gun can be elevated without having to worry about collision between parts, arms of the gun carriage can be displayed either open or close, the plate where everything stands on can be oriented in any direction.Regarding the scale, I honestly don't know what are the measures of the original weapon and because of that it doesn't have an specific scale, you would have to take the risk of printing it at any scale.
