Rain Stick

I recently got hooked on listening to this noise, it's really captivating. It may not be ear-shatteringly loud, but it does create an impressive amount of sound. Printer Settings Brand: MakerBot Printer: MakerBot Replicator 2 Rafts: Yes Supports: Yes Notes: To fit the rain tube properly, spheres have to be scaled. I printed several sizes and elongated some using scaling on the Makerbot, which added randomness to the sound of balls tumbling through the tube. This assembly requires three components: one middle rain tube, two joints, and two raintube assemblies with no cap. The result is a stick that's roughly two feet long. For longer sticks, just add more joints and tubes – you won't need a cap. On its own, however, a single tube requires an end cap to seal the opening for spheres. How I Designed This Concept To create random noise patterns in the soundstick, I designed a mostly random profile in Inventor then used the Revolve tool to generate peaks and valleys within it. With pieces fitting together using a joint, time could be added as desired – and sticks of various lengths can easily be created. The spheres add to the pattern of sound, randomized in size and shape.
