This is a bundle of two printable Trumpet mouthpiece models that are equivalent to a Bach 1-1/2C and a Bach 1-1/4C.

Creating my own models and printing them has saved me many hundreds of dollars in mouthpiece costs. The sound is obviously different than a metal piece but in terms of getting a feel for a mouthpiece and purely for testing purposes this is a huge money and time saver. Included in this is a classic body style and a body style optimized for 3d printing.

Mouthpiece Specs (in inches):Bach 1-1/4C:Inner Diameter- 0.693Outer Diameter- 1.079Throat- 0.147Cup Volume- 0.0769 (cu. in.)

Bach 1-1/2C:Inner Diameter- 0.681Outer Diameter- 1.070Throat- 0.144Cup Volume- 0.0732 (cu. in.)

I recommend printing on a resin printer. I print them on a Photon Mono 4K at 0.050mm layer height or 0.020 for less post-print polishing.For best results sand the rim of your print until smooth using 1000, 1500, and 2000 grit sandpaper then polishing using beeswax or another safe polishing compound.

This model should be printed at a total length of 87.27mm for the 1-1/4C and 86.95mm for the 1-1/2C to be dimensionally accurate to the reference mouthpiece.
