Any 3D printing you do for sprockets and gears, will fail much quicker than their metal counter-parts. The only luck that my team has had when it comes to 3D sprockets and such, is when it's used in light-use areas. Using a 3D printed part within the drive-train is bound to fail quickly, even if its printed in solid plastic. I can go back and find pictures if you would like of our sprockets that were turned into ninja-looking stars, from just practice on our field at school, with no defense.
The wheels you listed, that you are trying to print, like to fail quickly when hit. If you are truly going to print them, make sure that another robot can't get to them.
All in all, we still use alot of 3d printed parts, but in areas that dont have a lot of stress related with them.

I hear you. There is no question, metal parts designed for the purpose will be better than 3D printed ones. But when choice is 3D printed or nothing (when there no money for it) I'll pick 3D printed.
As for mecanum wheels. I am not sure if manufactured plastic wheel would be that much better 3D printed ones, so I figured both needs protection.
Have you tried 3D printed mecanum wheels?
