Be sure to check out my improved design that features a low B-flat hole: https://www.thingiverse.com/thing:4572413
Update 2021-01-06: for version 3.5 I've adjusted the tolerances on all of the joints to 0.2mm. You may have to apply a horizontal expansion in your slicer settings to print this correctly on your printer. Here's one you can print ahead of time to check your machine and filament: https://www.thingiverse.com/thing:4552242 simply find the number for a tight fit, and if it's less than 0.2mm then set your horizontal expansion to the difference. You will still have to sand the joints as that is the best way to get the perfect fit.
Based on cymon's recorder that plays well except for the very lowest notes. I made the bore larger to accommodate more airflow to get better volume at the bottom of the range.
I also adjusted the placement of the holes. Recorders are notorious for having some notes off key and I wanted to remedy this. (True you can adjust airflow to tune each note but this way it's more consistent and less to remember.)

For version 3.4 I've included separate soprano and alto STLs. If you scale the soprano up to alto size (150%) the size of the fipple will require a lot of air and it will literally take your breath away, however the remaining parts will work fine. I will likely at some point design a tenor (200%) version however that is a >2 day print. In theory the alto STL scaled up to 133% should produce a tenor recorder, however the fipple might have to be further narrowed and the finger holes may have to be made easier to reach.
