Fox Box Armoured Truck Wheels

It still amuses me that the complicated stuff I sculpt is so easy to cast but chunky regular shapes cause no end of problems.
This feels like the third attempt at these damned things but I think I've cracked it at last:


They're available as 2, 4, or 6 wheels (with the price per unit going as volume goes up, as one might expect):
