[GreenKeys] Model 15 keyboard gear ratio

[E.]

I can’s speak for the 7.42, but going out on a limb on the ratio… since your keyboard is tied to the main shaft and especially if you print as you type (even if you don’t)… your main shaft and keyboard ratios need to match or else they’ll be out of sync while typing.
