The 4 gears have double-octagons in their centers. This allows printing, swapping, and rotating the gears to place on the octagonal shaft to adjust the tempo by whole or half steps. The "drum set" I created is somewhat lacking and everything sounds similar to me (I'm quite hard of hearing). But I wanted to make this fun and fun was had. I am content. Requires some 3/16 inch rod. The crank requires printing with support material. The rest of the parts do not.
