CVT Transmission
Still a work in progress but you get the idea, just a general cone design CVT transmission. Will be adding more to it later. let me know what you think. If you do make it, let me know.
UPDATE
Changed some of the parts so they have better fits and print easier. Also added a top input gear option so you don't have to raise the entire assembly up or if you just want another gear. Will add a shifter soon.
