Our group now has a 3D printed version of the V150 available at Shapeways, in 1/56 scale. It's the 20mm turret version, but within a few months we'll have one with no top hull plate, so you can easily scratchbuild the APC, command, mortar, TOW, etc. variants. We'll probably also leave off the wheels and make them a separate item, since they make up a surprising amount of the cost and can be replaced by wheels stolen from some diecast model truck.
