Guiro

This is a 3d printable functional guiro (percussion instrument). It is printed in 3 parts. The biggest part is 161mm tall and 111mm diameter. I have included a measured drawing in case you are unsure if it will fit in your printer. Mine was printed in PLA, and I see no reason to use any other material.

The guiro sounds fine, and can be loud enough to cut through an 80 person wind band.

I have included the fusion 360 file as well as a STEP file if you feel like changing the design. However the fusion file is likely to break if you change it, because fusion for some reason does not always recognize all the surfaces even if they did not change.
