If you need to check if something is at or about the golden ratio. If you don’t know what that is you don’t need these.
Cut the inner holes first then the outer outlines.
As you can see, I’ve done these in two different materials so they should work in any of the 1/8"
The basic shapes came from plans offered by King’s fine woodworking but I had to completely rework them for laser cutting.
I have included the Fusion file as well as an SVG so if you need to tweak the hole size or something.
I used 1/4" Chicago screws from Amazon.

It’s lovely even if I don’t need it! Thanks!
Make them and you will find a use for them. The golden ratio is everywhere and is naturally appealing.
My goodness but those are lovely
Cool! Looks like the center-finder from way back when here on the forum.
Wow those are really great
Sorry couldn’t resist…
I didn’t know what the Golden ratio was until a few days ago then I saw your post but without an explanation. It’s a 9 minute video but well worth the watch.
I have been looking for that center finder. Is it still up somewhere?
I couldn’t find it either…
Here you go. Our first public beta tester did these.
Has anyone tried the linked golden ratio caliper plans? I’m unsure if the plans are off or if I am misunderstanding their purpose. I cut a set and tested it against various phi images including https://upload.wikimedia.org/wikipedia/commons/8/8e/SimilarGoldenRectangles.svg
It seems slightly off. Whipping out the measuring tape:
when the narrower side is 3", the wider side is approx 3.75" and if I am understanding phi right it would be approx 4.85"
I made this one, verified the geometry…

Now I feel like making yours just to see. What did you use for pins?
Picture hanging nails with brass heads.
I printed mine quite a bit smaller than the SVG I uploaded, just to fit a scrap of chipboard I had next to the machine to test. The nails were a tight press fit.
