Quick maths puts it at 160mm wide and 380mm long-ish. There are a few (more than a few) problems with the drawing too, the author hasn't properly accounted for the angles on the plates properly so I'd have to fix them and no doubt some other bits won't quite add up.... At that size it will need to be printed in chunks. Probably only get two corner hulls in one print and the central hull will be 4 or 5 plus turrets! Madness....!
Oh and they are nothing like T-34 hulls at all. They are longer, wider and taller.
