For some unknown reason, I saw these and had to have a set. I downloaded a set of plans but they were raster PDF and would not load into Fusion so I have gotten a good workout with this. First I put the PDF into Inkscape, did some tracing, imported that svg into Fusion 360, cleaned things up a lot, tweaked the length of the center pointer then imported it back into Inkscape to color code! So even though this started with someone else’s plans I still had to earn this.
EDIT: link to plans for those who see this but not that:
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 twe…
Nice job. There’s a set or two here from someone back in the PRU days.
I did a search but came up dry. If you have links it would be appreciated as I won’t post mine if the earlier ones are better than mine.
Nice, I like your design. I just happen to make a pair a week or so ago. They are not the greatest (pivot points too loose) so I would love to see other ideas.
(pivot points too loose)
I just posted these in the free plans area. This is why I always try to work in Fusion 360, I had to mess with the hole size myself but by using a parameter they all updated at once!
It was either
@jkopel or @henryhbk I think who made them. Don’t think they used the same name for them though.
I downloaded the files at the time but would have to dig around to find them.
There are these but they are not the same thing.
Edit: well crap, now I’m going to have to make some even parts dividers to go with the golden ration set.

Very cool looking calipers!
(slightly “War of the Worlds”.)
Memory isn’t what it used to be
Right there with you bro.

Nice calipers, and some even part dividers would be pretty good too!
“First I put the PDF into Inkscape, did some tracing”,
I hope you used Trace Bitmap in Inkscape. Nice Project!
Oh, I wish! I don’t know what was with that PDF, wouldn’t even open in Fusion 360, wouldn’t trace in Inkscape. Had to literally trace it out using the bezier tool then I put that relatively poor SVG into Fusion where I could clean things up nicely, then back to Inkscape for color codeing .
That was an epic topic. It is what got me hooked on Onshape. I made a chipboard copy of it, but never got around to the acrylic one.
Interesting to hear others workflow. Thanks
To be fair, I usually start in Fusion 360 but this particular project forced me to go back and forth.
I’ve been doing, Photoshop: export to SVG, then Inkscape with good results, for me anyway.
Wondering if this was your inspiration? The laser cutter sure makes it easy.
Yes, exactly, I mentioned it in the free plans post but failed to here.
Well after you have the file worked up! That is why I shared my iteration; not everyone should have to spend hours perfecting the file. Spend that time perfecting something else and share it.
