Traxxas Slash Wheelie Bar

I wanted a wheelie bar for my slash while still using the stock bumper. I designed the bumper to use part 4976, I have not tested any of the Traxxas aluminum wheelie bar wheels but they should work with the use of washers. You will also need 2 M3 lock nuts and 4 M3 screws 20MM long. I printed mine in pla with 100% infill and it has held up ok but you probably want to print it in something more impact resistant.
