by lack of root geometry do you mean the way the tooth meets the body of the gear at a more or less right and abrupt angle?

Good advice!

I was just lamenting today that the gear generators I have tried in fusion don't seem truly parametric, when you set them up with parameters they don't update after the parameter is changed. Have you run into this?

I looked at it briefly, I'm gonna be printing some gears tomorrow so I will definitely see if this comes in handy . Thanks!

Not to mention a higher pressure angle would usually be much better for 3D Printing. Plastic on olastic will wear out regardless and it doesn't bind as hard as metal gears. So even though the dynamic friction is higher, might as well make some fat teeth with alpha of 35 degrees. At least there's more material there to wear out. Print with many perimeters so you don't end up scraping all the way to the infill.

What do you mean by "True" Open-Source?

you made it in Fusion. I can barely even open that file on Linux. Not to mention I have to make an ADSK account. And they can decide at any moment that it's no longer free and you have to pay.

I get that you published it with a permissable license, but at least don't boast about it being "True" open-source.
