Summary

I printed the inside of the wheel with PLA and the outside with soft PLA. I also added a groove along the outside of the wheel to add more traction (makes it easier to taxi). It is very easy to scale the wheel up to the desired dimensions making it usable for different scales of aircraft.
Here is the link for the YouTube video where I assemble it: https://www.youtube.com/watch?v=2eh2LEMnLIc&t=9s
I hope you enjoy this simple 3D print as much as I did!
