I've customized version for large shank tenor trombones. In first tests it sounded much like the JK 7BL I took the measurements from. Parameters can be found at http://www.thingiverse.com/thi...

Here are the measurements I took from my Bb Helleberg mouthpiece, but I don't think this works real well for tubas; it looks kind of derpy:

Instructions

I print these with my Makerbot Replicator: in ABS at 20% infill and 0.15 mm layer thickness and sand the rim with fine sanding paper (400). Let me know if different settings work better.

Use OpenSCAD or Makerbot Customizer to get your custom mouthpiece.

I have included values for:
Trumpet (Fist hand tested)
Trombone (Let me know if these are good values)
Please let me know good values for Tuba, french horn, etc. Everything is in mm.

I've customized it for you: http://www.thingiverse.com/thi...
I'm not sure if it will fit, because I don't have a T-bone.

Also the STL is now added to this page.

I'll test out some configurations for a euphonium mouthpiece when my printrbot gets here. The fact that you made a customizer version is great :D

Don't forget to post the parameters when you get them. The backpipe is one of the first ones you want to get right. Have fun!

What would the measurements be for a Bb tuba mouthpiece?

Very nice! I would like to make one for a trombone, do you know were I could get the proper measurements? googled it but didn't find anything.

Robo on Jan 26, 2013 said:

I have a Trombone hanging from my ceiling, I'ts now a lamp, so the lamp wire goes through the mouthpiece, making it hard to measure.

Try this:
CupDiameter=21;
CupDepth=16;
CupSphereFactor=0.5;
RimWidth=8;
RimRadius=3;
ThroatRadius=4.5;
ThroatDiameter=5;
BoreDiameter=11;
FrontPipeDiameter=15;
BackPipeDiameter=12;
MouthPieceLength=88;
PrintingFootHeight=1;

Print it and check the size with your existing mouthpiece.
Most critical parameters are:
- Pipe diameters (this is the cone that needs to fit into your instrument).
- ThroatDiameter This is the smallest hole your air passes through.

Everything is in mm, so why not measure an existing moutpiece?
