Just made this for my 8th scale buggy because they break so easily and are like $20 a pop. I suggest nylon if you intend to use it on an rc car. I plan on test printing it in pla to see what setting/orientation works best then using nylon 910 since thats what i have. Bridge would probably be best though if u have it.
the +15 model is 15mm longer and a higher quality .stl
