The SVG file (very last and smallest image above) is all you need to make this. How many of those crescent-shaped half-rings you’ll have to burn depends on how thick your material is. Since I was using 1/4" wood, I only needed 6 rings.
Neat idea and thank you for sharing your file.
Practical cut right there!
Heh heh—works for any circular thing as well. Thanks!
Nice share! Thank you!
