I realized that I had no good way of mounting the thrusters to the t-slot. I decided I would engineer a bracket to snap fit into the bottom of the thruster pieces and then screw into the t-slot. On my second prototype I was happy with the result and decided to post it. The Stl file can be found here http://www.thingiverse.com/thing:1341956

Thruster isn't exactly level due to a print warp. A few screws should help with this
