Folded Tenor Recorder

thingiverse

This is a tenor recorder (more or less). Its range is about 2 octaves starting at C4, or middle C. It prints on my Ender 3 and Sovol SV07 (both 220mm x 220mm bed slingers).Some excellent small recorders, ocarinas, and flutes are already available. I am interested in print-in-place versions of lower baroque recorder voicings. If you're interested in model-based wind instrument design, check out pfh's demakein python module:https://github.com/pfh/demakeinWhile demakein does not appear to be maintained, France's INRIA currently develops the excellent OpenWind python module, which provides many similar capabilities and is associated with a number of helpful technical papers:https://gitlab.inria.fr/openwind/openwindMango Cats provided a clever solution to make long woodwind bores available for printing on typical consumer printers (with print volumes on the order of 200 mm per side). Their openscad file generates a folded bore, adds a fipple, places holes, and allows for customization of many parameters. This produces a nice print-in-place recorder with no joints to fuss over, but requires the inversion of left-hand fingerings. I did not find this prohibitively difficult, though. I hope to augment the folded tabor openscad file a bit to allow for additional bore folds while still placing holes in reachable locations. This might make print-in-place versions of basset and great bass recorder possible (though the results would be even more boxy and bizarre than these folded alto and tenor recorders).2024-03-24 update:Spectrogram of a scale recording on this recorder with the target pitches overlaid in dashed lines.
