So as I was weeding a little Thick Walnut Plywood keychain project I noticed these little… notches in the sides of some of them…
So at first I thought I had something weird in my cuts! But, as you can see, the holes are just in the side! This is the bottom of one of 'em.
So then I looked at the sheet… Check this out! A hole straight through!
And… It doesn’t stop! Here’s the bottom of the sheet!
So what say ye, Glowforge Support?
