My designs and models for download

Hey everyone,

Here are my designs:

 My first design started from the concept of a sting ray:

My second design went in another direction, but it helped to really spur some great creativity that lead to the final product.

The final concept:

With incorporation of the lego pontoon:

And we get this:

I think it looks awesome. But I would love your feedback. 

If you take a look at the back of the holder for the arduino, there is an additional plane. That hole is directed downward at a 30 degree angle from the horizontal x axis. We can use this to mount the motor. The future designs will include pretty much everything. 

Post your thoughts.
