BattleTech Hex Base, compatible with pewter mechs

BattleTech Hex Base. The standard base matches the dimensions of the Catalyst bases. The pewter mech compatible base includes an oval cutout for the metal base.

If you know of any other configurations I should offer, let me know! There are a lot of pewter models out there with oddly shaped bases that could be accommodated.
