Wood Lathe 6" Jam Chuck

A 6" Jam Chuck I printed with TPU. Print with Build plate only supports, and I printed it at around 75% infill because I wanted it super dense. So far it works a treat, fits in a 4 jaw chuck with a 10% dovetail on the tenon. I suppose it could be scaled up even, as long as your chuck jaws can go wide enough to still hold it.
