This is a small shank trombone mouthpiece that has been designed to provide a large dynamic range and a unique, plastic tone. I have personally tested and found it very playable, it really just depends if you like the more subtle sound that plastic gives compared to metal. I would recommend lightly sanding the rim of the mouthpiece if you print it as I find that despite the fillets at the base the mouthpiece is still a bit sharp simply because of how is has to be printed. Print Settings: .1 mm layer height

supports should be enabled for best cup quality on the inside of the mouthpieces, but it will print successfully without them

100% infill
