you mean the mounting plate/footprint thingie? There's a visio stencil for that in the downloads section i'm fairly sure. (and i'd be surprised if Oscar hadn't included it in his excellent 3d/CAD diagrams...)
if you mean a template for the football-esque shape because you ARE NOT using a mounting plate... i don't see why you wouldn't just trace around the base *shrug*
does that help a little? or could you clarify?
