Those are awesome Steve!  Thanks for the write up.  I’ve contemplated carving one if just the right stump or limb comes along and I’ve 3D printed a couple.  Never thought about crafting one this way but now I am 😎

In my limited experience, you’ll probably never get one that works right for any nimber of any type of any size dice.  Too many variables.  The exit seems to be the trickiest part along with making the basin deep enough to catch them all but not so deep they’re hard to pick up.

Great work, great design and nice woods!
