Finger paddles for swimming

Finger paddles are a type of hand paddles used to learn proper swimming technique.

There are two versions with different hole patterns. One is better suited for straps and the for rubber tubes to hold your hand in place.

I have also made a design for larger hand paddles (small and medium size) which can be found here: http://www.thingiverse.com/thing:683409

Here is one example on how to use this kind of paddles: https://www.youtube.com/watch?v=E1EaFbvOZ4I
