Marble Slab Wedge

A friend of mine has a business where he sells slabs of all sort of rocks, he told me the wedges he had wore out and was using a wooden wedge because they weren't easy to get a hold of. so he showed me the concept of what he needed and I designed my interpretation of if, I just gave it to him and he put it to work immediately, hell give me feedback soon. I printed it with generic PETG, 12 wall layers and no supports, the surface finish on the bottom is not bad, it won't win any awards, but I don't think its something that needs time and filament wasted on supports.
