I made this in the hopes of making a toy where i can throw a ball at it, and the ball will go a random way causing my puppy to chase it. I tried to reduce the use of filament as much as I could. All of the parts should be able to be glued together. Each piece takes around 3-4 hours to print. Next time i might make a smaller one. Let me know your thoughts.  I added a funnel in case your dog doesnt know how to put a ball through a hole, and you want to throw a ball at it.
