This is a reinforced version of the C10 zero offset bumper bracket. It is desined for use ONLY with the SCX24 C10. The bracket bolts right on in place of the stock bracket, but only after the body post height is adjusted to the uppermost posiotion. I printed this with 15% infill, 2 walls and no supports. Depending on your printer, some cleanup may be necessary to make it fit properly. I would also recommend using PETG filament, as it will hold up better to impacts.
