Just a simple ball thrower for playing catch with your dog.

This is a single-piece model, printed in TPU, which is great for gripping the tennis ball and storing the energy from the throw. The back segment is designed to abruptly stop the tennis ball holder and release the ball with explosive force.

Performance-wise, it worked better than I expected—I was able to throw the ball about twice as far compared to throwing by hand, and without much effort. I would argue that it could work with PLA too—maybe not quite as well, but the option is there.
