222 would be happy to have you come visit our pit in Galileo!
Since I am a sponsor and mentor of 222 I will be in attendance at the championship.
We have a wide assortment of 3D printed parts on our robot this year. Everything from sprocket spacers to frisbee launching device to bearing blocks.
Here is our original frisbee launching device in the lower area of the picture. At the end of the build process we figured that it was critical to redesign the "pushing" device to allow for frisbee stacking. We were quickly able to 3D print a new design that was shorter and also wedge shaped so that the forward motion pushed the frisbee forward into the launching tire. The backward motion is where the wedge shape came into play by allowing the wedge to push the stack of frisbees up and over the pusher device to fire the rest of the frisbee stack.

If you do happen to be interested in speaking to me and I'm not in the pits when you stop by just ask for a team member to text/call me so we can find each other.
