This is well suited for making more decorative style gears for cutting out on the laser or with a CNC router.
I’ve played around with the demo a bit, but obviously wasn’t able to actually make anything based on the design. I wasn’t able to find anything else out there to accomplish the same purpose (and I believe that author of the software was in the same boat and that was part of the reason they designed and then “commercialized” it.)
Would love to find/create an open source version, but that’s a different topic…
