Classic Warhammer 40k biker base

I was talking with somebody at a game shop the other day and we were lamenting how hard it is to find the old style biker bases for 40k. Some quick tinkerCAD and here's a super basic base. When I get some free time I might make something with the correct angle tapers on the sides and all that. For now at least this will give you the correct dimensions to replace a base.
