I'm really enjoying figuring out how to play the 3D Printed Rackettby PyroSteel, so I wanted to better see how the holes connected to the pipes.

So I did some quick booleans to expose the internal pipes and holes of the rackett.
I also added some cylinders as arrows to indicate the direction of the breath.

This helps me see where my fingers need to go. Maybe it helps you too?

Also, I made an adapter to attach a Bari Sax mouthpiece, which I find easier to set up and play. If you play bari sax, this might be a fun approach for you too.
