Up your game in laser engraving Stainless 20oz Tumblers with this tumbler holder that fits rotary chucks. I designed this to have very tight tolerances as it need to be to keep tumblers from slipping off during rotation. When you put the tumbler on it is very snug and that's the way its supposed to be so wiggle the tumbler a bit to go on and off, if its to loose it will slip. The tumbler holder goes on the chuck with the prongs over the outside, slightly tighten the chuck with chuck key and just put the tumblers on and off. I will have other sizes available soon. This comes with supplied gasket. You can also use the gasket from the tumbler you use to get exact fit if needed.
