Trumpet Mouthpiece Puller

Twice in my life I've needed a tool to extract the mouthpiece from my trumpet - when I was 10 years old and 40 years later.  What do you do when you need a tool, have 3D modeling skills, and a printer?  Make a tool yourself.

This is modeled to fit my instrument.  It might work for you or you can adapt this one or build one from the ground up.

The bottom piece (blue in the image) is split into two in order facilitate assembly around the lead pipe.  The screws are sized to hardware I had on hand. 10-24.  Washers simply provide a solid surface to push against.
