Tank Merkava MK 4 3D Printing Model | Assembly

This is the new authentic 3D printing model of the real Merkava Mk 4 Tank, which was used by Israel armed forces. Feel the power of one of the mightiest armies of the world!
 
For the first time, Merkava tank was used in Lebanon war in 1982. It was developed to be fast, keen to ride the off-road and to be repaired easily as fast as it is possible. The decision to resume the manufacturing of these tanks was made in 2013, and before that they were used in another Lebanon war in 2006. Advanced machines of this line have modular armor design, which helps to replace only its damaged parts. Merkava Mark IV is the most recent model of its row and the most advanced one. Its series was limited, and the last tank of this model joined the Israel army in 2004.
 
Inspired by the success of Merkava 2 tank 3D model, Merkava Mk 4 3D printing model is created, and it is designed to look almost exactly like its prototype. The figurine looks so realistic that it seems to be ready to go to the war. The internal layout of the tank is, unfortunately, a military secret. But there are enough photos to make it close to the original. The scale of this 3d model is calculated from Merkava's actual length including barrel gun (9.04m) and is 1:38.

There are some details that are movable in this 3D model. The tank’s cannon rotates 360 degrees. Its doors, its hatch open and close, road wheels and caterpillars move. The model has an active suspension that fulfils irregularities. 
 
After being 3D printed, the 3D model will stand 97 mm wide, 84 mm tall and 240 mm deep.
 
This is the 3D model that requires assembling. It is split into 84 pieces, including 2 spare caterpillars and 2 pieces of armor. You can watch the video at Gambody YouTube channel that will make this process easier for you.

You can also print the springs from the flexible plastic, but in order to achieve the high quality of the suspension, we recommend to use the metal springs from ballpoint pens. Then the suspension will work the best and the most realistic.
