Cheap ROV Thruster

I've redesign the mounting system a little bit. Now, rather than using round headed bolts that you have to epoxy into the thruster, you can now use hex headed bolts which slot into the newly designed holes. Because they're hex shaped they will no longer rotate when you're trying to attach the thruster to your frame - even if you didn't epoxy them. It's just better.

I printed a sample piece to make sure it all works, and have updated the STL.

Added the STL for the anti-clockwise prop. You could just mirror the original prop before printing, but this save you the bother.

My ROV projects are based on the ServoCity aluminum beam system (see https://www.servocity.com/structural-components/channel/mini-channel). As such I have adapted the mounting system on the Thruster to match the spacing of the beams.

If you want to copy and edit my thruster changes to accommodate your own motor, you can find it on OnShape here: http://bit.ly/2g0tdvf
