This is a first stab at a simple 3-tone "jam block" type of percussion instrument.

Hold the handle, grab a stick, and whack the blocks. I got inspired to try this by realizing some of my larger PLA prints had a nice resonance when struck.

It actually sounds quite nice, printed in PLA with 10% infill.

A nice thing if you want some new sounds and have some unloved filament to use up.
