Stir Xylophone

Slide in the handle, glue if you desire, then "stir" the mallet around the inside (or bang on the outside, I won't judge).

I saw the challenge and decided to find and build a fun percussion instrument. Probably won't win for decibels, but hard plastic makes a unique sound when you use it in place of wood. Printing with different angles and infill levels will also change up your resulting music.
