Ring Frisbee

This is a fun ring frisbee to play with friends and family. It has a flat base for easy printing without supports. The model has a diameter of 160mm, however, you can scale it to the size you require.

Though it shouldn't really need to be said: CAUTION - Throwing a hard plastic ring at someone can result in injury if not used with care.
You could reduce this risk be printing using a flexible material such as TPU.
