Tenor folk shawm
by pfh, published
The shawm is the loud medieval ancestor of the oboe.
This shawm has a simple six-hole fingering system. I am particularly pleased by how this model turned out. The finger spacing is not too wide (32mm between holes), and it can play a solid octave and a half.
The pitch is similar to soprano voice (tenor plus one octave).
Thanks again to John Boshua for an excellent print in ABS plastic.

Depending on the capabilities of your printer, print the instrument as a single object, or in two segments, or in four segments. I've provided STL files so that you can print the segments in a single run or separately. The shawm in the photos was printed from ABS plastic in two segments, with an 0.1mm layer size.
Make a drinking-straw reed using the instructions here: http://www.instructables.com/id/Practice-double-reed-from-a-drinking-straw/?ALLSTEPS
The straw should be 4-5mm diameter.
If the joints don't quite fit together, sand them a little until they do. Use some sort of grease to make tight seals between all the joints, and with the reed.
The fingering chart is straightforward: http://www.logarithmic.net/pfh-files/design/folk-shawm-fingering.pdf
More sizes of shawm, and designs with a more complex fingering system similar to recorder, are available in the "pre-built" design pack downloadable from: http://www.logarithmic.net/pfh/design
