Impractical Differential Swerve

I took inspiration from Trevor from 2471 when designing this (a lot of inspiration), but tried to make it my own through changing things small things for that 1403 twist. I also swapped it out for a 4 inch wheel for something a little more standard in FRC, and also had the gears roll on a shoulder bolt rather than a standoff you would press in. To attach the shoulder bolt, I used a threaded insert made for pressing into plastic that i pressed into the bottom 3D Printed part. I felt like using a shoulder bolt would be the easiest solution.
