I’ve considered 3D printing, as I’ve designed and printed gears in the past for other applications. Gears are always a pain though and require several rounds of design, printing, trial fitting, tweaking, etc. That’s why I was wondering why anybody already makes a gear set before I put in the effort.
You'd be better off running stock gears with some adjustable motor mounts for larger pinions imo. I've raced my clods on off-road tracks quite a bit through the years.I like a 6.5T sensored motor with a 14t pinion and stock internals, but if you have something like a clodzilla chassis that's probably going to be way too much motor. What motors are you planning to run?
I've seen adjustable motor mounts that allow up to 22t pinions with some dremeling of the gearcase for clearance. That should be more than enough gear.
