My son is just coming to age for playing marbles, and we recently bought him a set.
The thing is: he doesn’t know how to play marbles… so we had to teach him 
On this occasion, I discovered there’s more than one way to play…
Personally, I was playing “long distance” over concrete, aiming for a hole or dip in the ground.
My wife, on the other hand played on manhole covers, aiming at the center, carefully navigating through the maze it formed
Today, she found this product:
basically, it’s a silicone mat that mimics one of those manhole covers, but it can be folded and is probably a lot lighter for a kid to carry 
So, what do you do when you have a CNC and your wife shows you something like this?
The design is pretty straightforward and I used one of the pictures as a canvas
Then it’s just a quite simple machining, although F360 had a really hard time navigating through this maze trying to build the adaptative clearing toolpath
Note: I found a better/faster way to machine this, but that’ll be for the next one…
Quick coat of paint, and it’s good to go…
Nex step is to test this out tomorrow with the kids, and maybe if I feel brave, try to machine a mold and make a silicone cast…
I made this one out of MDF, do you think it MDF can be used as a mold for a silicone cast? or should I use plywood? hardwood maybe?
