Here is the design I made for day 11. It’s a marble game. This is another one that I have not cut yet. I’m back at work this week, and have less time to actually make things. I’ll update this post once I have one.
I ‘pinned’ a few of these years ago and still haven’t gotten to it. (I want to make a big one as a yard game.)
Love your desk top version. Regarding the “inside”… certainly easier to just cut the ‘channels’ out of one sheet… but I wonder about wasting material (it kills me when I have to)… couldn’t you just cut a few straight pieces and glue them in place, since it won’t be seen once assembled.
