I've had this odd little part laying around my desk for some time - does anyone know what it is? There's no Lego logo anywhere, and I've searched BrickLink somewhat comprehensively, so I'm guessing it's from a compatible set.
It's a modified 3x2 plate, but without a hole, and the red bottom part is sort of a rubbery, grippy substance. The "cover" is softer, non-ABS plastic, and can snap onto the plate either way.
I'm guessing it came from my wife's nephews in a whole pile of stuff they gave us - mostly Lego but there was some MegaBloks stuff mixed in too. Probably not from after 2000 at the very latest.
