Recorder to PVC Pipe Adapter

I made this adapter for my air pressure based rocket launcher. With just a little air pressure I can make my recorder produce sound.

I printed this using TPU. It doesn't look super great, but the adapter fits snugly and works surprisingly well. If you print this the hole for the air to go into the recorder might not print right because of the way it was designed, so you may have to poke a hole to let the air to go into the recorder from the pvc pipe.

This is designed to fit a 1/2 inch pvc
