Summary

Modeled after my Bach Megatone mouthpiece.

Instructions

Print out in high resolution and solid fill.
This mouthpiece models well in plastic as the Bach Megatone has twice the material in it than does their standard 7C model.
My print of this mouthpiece needed a small amount of sanding around the cup. It inserts about 1 inch into the mouthpipe.
In playing, its sound isn't as vibrant as the original in the lower notes, but surprisingly it is somewhat more responsive when playing above the staff!
I imagine it'd be good for playing in cold weather.
