A set of three target rings for pool and challenge course competitions using OpenROV and the [QuickClip hook](http://www.thingiverse.com/thing:1557056). Challenge your friends to an underwater robot Olympics using small, medium, and large target rings.

Zip tie fishing weights to one end and any buoyant 3D-printed thing to the other end.
