Inspired by the following posts:
I created a quadruple spiral version of a laser-cut wooden spiral bowl. The Thingiverse SVG file I started with needed mods to the legs to more evenly space the spiral cuts in the frame. I may fiddle with the frame some more.
I cut two sizes of the bowl, a 9-inch one in PG draftboard (~20 minutes) and a 5-inch one (pictured above) in PG basswood (~10 minutes). I like the smaller one best.
Time to break out the “high dollar” walnut! I’m thinking Christmas gifts that can be mailed flat—in an envelope.
Feel free to make changes as you see fit. Both of my SVG files are in the following ZIP archive:

*8/22/2018: A minor change to the 5-inch SVG file to strengthen the area around bowl’s center 1/4" square hole.
