Shakuhachi flute

thingiverse

This is a 1.8 shakuhachi, Japanese bamboo flute, with high playability. While it has a simple modern shape, the inner tube (air column) is modeled based on a real instrument. Check the following video for a quick introduction of the instrument: https://youtu.be/t5EyfudbpyA 3D Printing Make the wall thicker (preferably 4 lines or more) in order to prevent air leak. The wall thickness would also affects to the sound. The infill is suggested to be around 30%, which would make the instrument about the same weight as a bamboo made instrument. Post Process To get better sound, give some extra time to do post-process on the printed pieces. There is a sanding block model included to help some of the work below. First, smooth out the joint parts so they fit together with slight force. Do not sand the parts too much, or they will go loose and cause air leak. Next, sand and smooth the inner wall. Even better finish the wall with a clear coat paint, which would also prevent air leak. Lastly and most importantly, reshape the front edge of the mouthpiece, so that the depth of the cutout goes about 4 mm or a little less. Finish with a softer sandpaper to thin and sharpen the edge.
