Here's a challenge for all the regular visitors here: Where are there good gears to download? Good gears, with good teeth!
It's a subject I see here all too often: users working with downloaded gears with absolute dreck for gear teeth. I have yet to find one decent configurable gear in Toolbox or 3DContentCentral that has gear teeth with a proper involute tooth shape.
Unsuspecting designers without enough knowledge are putting these gears into products with dreadful results. I personally know of multiple products that have had problems due to this.
I don't want to launch into another lecture about how and why this is vital. I just want to know, are there any good gears out there?
