Print came out clean enough. I'm not overjoyed with how clean the slits in the body are (cut them with a dremel), but they're clean enough and they work. I drilled four 1/8" holes and installed rivets to lock the body to the motor mount/fin assembly. Then I used a very light bead of 527 glue to fill the gaps around the fins. It's currently drying now.

Still need to get started on the launch mechanism.
