I remixed this bumper to fit the new Bronco TRX-4. it's a perfect fit and its strong enough to take some basing. I upload V2 which has a separate mount so if you have a hard tumble and break it like i did you can just print some spare mounts and not the whole bumper. If you have TPU print the mount with that and you will never break the bumper.
Added SCX10 mount
I printed this with 4 shells, 6 bottom and 6 top layers for extra strength
