After years of intense R&D, I'm proud to present the perfect musical instrument: The Fart Accordion.
You need TPU to print this beautiful one piece musical instrument. Empirically tested to be a very good way to annoy your partner!
Check the video of how it plays: https://www.youtube.com/watch?v=vrLfxlpuedw
How to print: Print the holey side on the print bed. I recommend printing it with 100% infill or enough top layers to get the finger side sturdy and airtight. Don't worry, it will still only take about 12g of TPU.
How to play: Place the holey side on your palm so you get a nice seal. Wet the palm for extra juiciness. Then squeeze the instrument with your fingers. Alternate angles, rotation, position, speed, energy and sensuality to make it rain! The instrument and your fingers might need some loosening first before you start getting nice sounds. Keep practicing and try different palm positions! #sharethefart
