After some looking around online, I wasn’t able to find a CAD file for the high strength 84 tooth gears. I was just going to use two regular 84 tooth gears constrained together, but it just wouldn’t have been the same. Anyway, I decided to make one myself. Feel free to download it and use it for your projects
Jordan’s CAD library already has it but cool.
Thanks for pointing that out. I’ve added a STEP file of the 84 tooth gear to the website. It can be downloaded along with the rest of the HS gears from this page.
As always, please let me know if something on the site seems broken, or missing!
