This 6mm battle mech, inspired by battletech is a unique and bespoke design, made originally as an example test build for the game Minute Mechs, it has varied weapons one of which visually represents a top mounted turreted autocannon of some form. The Sci-Fi design is industrial military erring toward a western idea of mech construction.
I've not tested this design, the top weapon might be too small to properly print - If you have any troubles LET ME KNOW and I'll try to improve the mesh.
Designed to print at about 40mm high on a 2.5 inch hex base, milage may vary...
