CAD Tutorial - create a prototype shooter/launcher

I had a request recently on how to create a shooter (or launcher if you prefer). I put this tutorial together to design a prototype system allowing you to easily put together a shooter using various speeds and compression rates that can be reused. I’ve used this with team 4152 many times over the years and we’ve found it very useful. Please note that I’m using motors that I have kicking around, there are obviously lots of options! If you have feedback or like it please reply - we use this information for our Impact Award submission.
