Stop Mute
The Stop mute is a classic transposing stop mute that produces a nice raspy sound. It is printed in two parts: the rigid body and a cork component. The cork should be printer using TPU or another rubber-like filament. The body sounds best using a hard, rigid filament such as PETG.

Parduba
Parduba mutes are straight mutes used by the New York Philharmonic in the 1920s. Originally made of brass, they produced a rough, aggressive sound and were never widely produced or adopted beyond New York. This design prints as two pieces, and the tuning tube simply screws into the mute body.
