Hop Ball Plug

thingiverse

We bought our son a fun toy called a "hop ball," but unfortunately, we lost the plug before we could inflate it. I came up with a creative solution since we couldn't find the missing plug - I simply printed a replacement one using a 3D printer in PLA material. To remove the plug and let air back into the ball or for storage purposes, you'll need to use pliers or any similar tool to grasp the "shoulder" of the plug firmly.
