When I was a kid my parents had one of these curiosities made out of wood. It was always fun to see people look at it and wonder how the ball got inside.

I just couldn't resist designing my own version and here it is.

After printing, place it on a shelf and see if visitors wonder how you were able to get the ball inside.

Removing the provided support requires the following steps:

1. Hold the cage in one hand and with the other slowly twist the ball. This will release the support from the cage.
2. Now, insert a small screwdriver or similar tool between the ball and support and slowly twist the tool while holding the ball. The support will easily release from the ball.
3. You will need to cut away at the support to safely remove it from the cage. It is a bit annoying, but easy and doesn't take long.
