Model of tank.

Model of a self-propelled artillery gun.
This fantastic self-propelled gun model was designed by a child.
For normal printing of the barrel and machine gun, as well as to reduce the number of supports, it is better to tilt the model in the slicer at an angle from 45 to 52 degrees.
Printed from PLA, 0.4mm nozzle, 0.2 layer, 3 walls, 15% infill, gyroid, thin tree-like supports.
