This is the same model as the earlier quad cannon, but this has been upscaled, basically doubled in size. Each quad cannon is:
Width:11.47 mm wide.
Length, back of turret to tip of barrel: 18.506 mm
Height, from base to the cannnon's highest elevation: 8.8 mm.
Due to the larger file size, I could only get 4 cannons in the assembly. Sorry, frosted ultra detail only,
