Universal Joint Print In Place

This is a model of a Universal Joint that I made. It's a start for my RC Car project. This can be printed in place with some support. I don't know much about Universal Joint yet, but I felt like I have to start somewhere. Download it use it and let me know how I can make it better, give me some tips. I made a video about this and show you how I make it on Fusion 360: https://youtu.be/mYuBx3rJhJ0
