Remix: Water Rocket Fins-Only adapter

I wanted to use kludgemonkey's water rocket fins, but without the NPT quick-disconnect nozzle. I remixed it to be compatible with a launcher that uses a 3/4" PVC to threaded reducer (with heat-shrink tubing to seal). It looks great! I'm going to have to launch-test this in the morning.

Looking at the preview image, it looks a little messy; it sliced and printed no problems in Makerware and on a Replicator 2X. Let me know if you have problems slicing or printing and I may try to recombine the component parts.
