A three-component printed assembly supplies the base shell, pusher, and nose cone for the Dixie Thumper Toob Tube aerial signaling round. Makers are directed to use eight walls, complete infill, and PLA filament in either ordinary or plus grade.

The finished parts accept ordinary cardboard fireworks tubes that measure nine-sixteenths of an inch inside and run from one and a half to two and a half inches long to carry the payload.
