Here’s a slightly different wooden spiral bowl:
I was inspired by this bowl on Thingiverse but I wanted to design my own from scratch. I did it in Illustrator (I’ll put together an explanation if there’s interest) using the Transform effect, then cut it out of Baltic birch (I’d love to use Proofgrade but it wouldn’t work with the water). Then soaked the piece in water for about an hour, then put in between two bowls with a weight on top and let it dry for a few days. Glued the red beads between each outer arm. That was pretty challenging. I’ve got an idea about how to make it better next time.
