What it does

Functional clarinet mouthpiece designed for experimental musicians
Perfect for DIY instrument tinkering and music cosplay projects
Inspired by professional designs but optimized for 3D printing
Great conversation starter for band geeks and maker enthusiasts
Originally modeled in SolidWorks for precision geometry

Meet the experimental clarinet mouthpiece for players who love to tinker. This 3D-printed design brings DIY instrument making into your hands, whether you're exploring alternate sounds, building a prop for cosplay, or just curious about how mouthpieces work.

While it started as an attempt to replicate a Vandoren B45, the designer pivoted to create something more suited to 3D printing's strengths. The result? A just-barely-functional mouthpiece that actually plays, perfect for experimenting, display pieces, or backup gear when you want to mess around without risking your main setup.

This design was printed on a Fablicator and modeled in SolidWorks. It's a fun project for band students, music teachers looking for teaching aids, or anyone who wants to see what happens when maker culture meets the woodwind section.
