This is a remix of the classic soprano recorder in C. It will play a half step or full step lower than the traditional instrument, without having to obscure the bell. It will also play in the upper register from Bb to high C, although the highest notes require more breath pressure and will sound loudly.

To play, you'll want to use all digits on your left hand and four fingers on your right. The only learning curve is playing F now involves lifting your index, not middle, finger, and changing from F to G involves moving both hands. The extra protruding hole at bottom plays low B if half closed (and all other holes closed) and low B-flat if fully closed. There's a resting notch for your right thumb for optimal hand position.
If printed in PLA, the tone will be warm, woody, airy, and flute-like, especially in the lowest notes. Some prints produce better lower notes than others and I'm not sure why; this was also true of the design I remixed from. PETG gives a clearer, somewhat brighter tone, but still very definitely a flute sound. I have not had luck with ABS for this design because even slight layer adhesion problems can produce a weak sounding or non-sounding recorder. For the same reason, I will not try it in PC.
