When you have a dog that loves playing ball, a thrower helps save your shoulder and keeps you from handling drooly gross tennis balls.
But carrying a 2 foot long thrower can be awkward. So I designed a collapsing thrower, so that it's easier to get to and from the park.
It works quite well, my dog loves it.
It has a small hook to allow you to use a rubber band to keep it closed.
Tennis balls work best, but it's compatible with any tennis ball sized balls (ChuckIt, Nerf, etc). I recommend lighter balls, as the heavier ones (for example the full rubber ChuckIt balls in the pictures) put more stress on it.
When extended it's about 2 feet long. When collapsed it's about 9 inches long.
Parts Needed:
It's designed to use an M3 bolt and an M3 heat press insert. Alternatively you can use an M3 bolt and nut or it's 1/8" imperial equivalent.
It can also be glued instead of using bolts, but that makes it so parts are not replaceable when they break.
