FIRST Robotics Swerve Tread

This is the swerve tread seen on a lot of FIRST Robots, it has a 4-inch diameter and is 1.5 inches wide

This model is best printed with TPU, I've personally had the best luck with Overture's 95A TPU

I did not design this model, it was legally acquired from Swerve Drive Specialties' STEP file of their Mk4i swerve drive assembly and can be found there
