Saxophonists take apart their instruments and store them in cases. Cases typically feature storage space for necks and mouthpieces, but lightweight soft cases and compact travel cases do not. Many saxophonists tuck these parts into pouches or cloths and put them into the bell when they use the latter type of case. Despite the conical shape of a saxophone bell, most pouches and cases on the market to date have been flat, requiring saxophonists to roll them up with the parts inside before putting them into the bell. We believed that thinking in 3D would help us make a much more convenient pouch, so we began coming up with ideas. First, we looked at a neck and mouthpiece and considered the most logical three-dimensional shape for them. Then we handcrafted a mock-up with a square bottom and a top that twisted 45 degrees, because we originally wanted the design to encourage the intuitive act of twisting. However, having four intricately twisting surfaces prevented the prototype from fitting snugly into a bell, so we thought some more and made more prototypes, finally arriving at a cone-shaped model that had only three twisting parts. We used wetsuit material for neck and mouthpiece protection and held it together with strong piping to help the pouch retain its shape and provide elasticity if it were dropped. We chose to make the piping blue to make it an accent that encourages the saxophonist to twist the pouch into the bell.
