? Hold on a sec first you're talking about motors now 3D printed parts...That’s a big oof but If I were you I would ask your tech ed teachers and ask them if you can 3D print them. I know that my high school uses 3D printed parts for mousetrap vehicle. The only thing is that you’d have to make the design for it to be printed.When you order multiple motors the prices add up...Just ask you're parents. After all, it's just $28.
I have 3D printed parts, and in fact my nats buggy last year was all CF and ABS. But 1. The 3d printers kinda suck 2. The tech ed teachers at the high school are rarely available
