Full disclosure: I’m a newbie, so this may be ho hum to a lot of you.
While waiting for my GF, I read a bunch of posts about living hinges. Never being one to leave well enough alone, I thought, “if wood can bend around a corner, why can’t it bend around all the corners?” 28 iterations later (I was trained as an engineer, my numbering system lets me know this), I produced the first finished version of what I was aiming for.
Each of the three designs - large wood, small wood, small acrylic are slightly different because of the properties of the material. The large wood box needs a locking ring around the top to keep the sides vertical, while neither of the smaller boxes needs that. Both of the wood boxes need a ring inside the top to facilitate ease of use, while the acrylic top works simply with a ring engraved in the top that fits onto the sides of the box.
Ah it’s just a bit of an in joke. It’s a pretty commonly used font, and you know how typeface geeks are. There’s a bunch of websites that rag on using it, and it was a joke on the forum to tease people for using it. (see also: comic sans)
That is an articularly nice living hinge design! making round things was the first challenge I went to when I first got my Glowforge. I did not understand about living hinges but have an oak cane bent at the top and so went off in that direction.
I did find that a deep engrave really stabilized the round, the ability to expand or contract the circle really helps as if the wood is solid any change in temperature or humidity really changes the diameter.
Also what I discovered was that a locking pattern could hold the ends together though it looks like you are just matching the design at the ends which could be why keeping it from trying to be an exclamation point takes some effort. Also, I have noted that a curved area of stress has a lot less stress than if the stress is focused to a point.
