I used to have a toy called a skip disc but it eventually fell apart, so I designed my own version, the Skipbee. It is kind of like an upside down frisbee. Print flat side down in TPU or some other flexible with only 2 perimeters so that it is reasonably soft and nobody gets klunked in the head or at least when they do it doesn't hurt too much. Lots of good fun. Here is the Skipbee in action. https://youtu.be/OI79mZPFx5c
