I am trying to fully plan out my team’s bot this year, but I am modeling from home, and don’t have the parts with me. So if anyone could help, would much appreciate it
Download the cad files and get the exact dimensions from those.

9motorgang’s solution is solid. Another way to approach is that the gears must match the .5" spacing of structural parts.
For the “old” gears, the 12 tooth is .5" and each size up is +24 tooth and +1 inch. So 12, 36, 60, 84t == .5, 1.5, 2.5, 3.5"
The “new” gears 24, 48, 72t == 1, 2 and 3"

And very often you don’t even need to doenload CAD files. You can use the dimension tool in the CAD preview on the website to select any faces or points to get a dimension.
If you think about it, shouldn’t the title be “can anyone tell me the diameters of the 84 OR 36 tooth gear”?
