Rotary Snare Drum

thingiverse

What's more maddening than a snare drum? A whirlwind, rapid-fire snare drum is even more infuriating! It works by attaching a ratchet-type noise-maker to a drum-like membrane. It's not just loud, but also disgustingly obnoxious. Several options are available for the ratchets, featuring varying numbers of teeth that create sounds ranging from an exasperating rat-a-tat-tat to a shattering drone. Who conceived this #MakeItLoud challenge in the first place?

Post-Printing Assembly Clean out any strings or leftovers on the drum left over from printing - particularly in the slot at the bottom and in the holes for the spinner handle. Snap the thwacker bar into the slot at the bottom of the drum. The bottom of the bar should sit flat against the bottom of the drum. Insert the ratchet between the arms sticking up from the drum and pass the spinner handle through the holes. Ensure that the oblong slot in the ratchet lines up with the flat sides of the handle. The handle and ratchet should spin smoothly. Give it a try! Be aware: this thing is extremely loud and may scare children and pets. How I Designed This The only tricky part of this design was figuring out how to attach the thwacker to the drum membrane. Printing orientation for the drum was fixed because the only reliable way to print a thin, strong membrane was to have it print directly on the build platform. With that orientation, printing the thwacker as part of the membrane would apply maximum stress to the weak layer lines. Printing the thwacker as a separate part on its side made it much stronger, but designing a clip into the membrane took a couple of iterations to securely hold the thwacker in place.
