- April Cools post about brass instrument physics and 3D-printing a playable trombone.
- Brass instruments like trombones are half-open tubes, normally producing odd harmonics, but mouthpieces and flared bells allow approximation of a full harmonic series.
- The 3D-printed PEX PrintBone uses PEX pipes, a metal mouthpiece, and printed parts; modifications improved durability and printability.
- The trombone works with mostly in-tune harmonics, similar sound to metal, but lacks an F attachment, using false tones for missing notes.
- Feedback from trombone players noted balanced weight and bendy slide, with potential future additions like a slide lock or water key.
