Tennis Ball Chucker/Thrower

Update Jan 9, 2023: Fixed issue with the top screw hole being out of alignment.Tennis ball chucker remixed from Ball Chucker by cperiod.  I added a few places to add screws to hold the model together after I split it in half. It prints easier when printed this way. I also added a handle. If the ball is too loose you can put the end of the chucker in some boiling water for 10 to 15 seconds and bend the end a little to make it tighter.You need a piece of ½ in (16 mm OD) PEX tubing that is curved slightly. The curve helps the ball release better from the cup. Takes a little practice to launch the ball nice and high but it does work. One thing that is nice about the design is that you can pick up the ball from the ground with it and avoid a slobbery mess.Glue the tubing to the handle with hot glue. Worked well for me.Bolt together with M3 bolts and they should thread into the plastic firmly.The ball cup actually has threads for a broom handle but I find the angle incorrect for the straight handle which is why I used a curved piece of PEX water tube. The hardware store will often sell this by the foot so you don't need to buy a whole roll for this little project.My dog loves it which is the important thing.
