Tin Whistle / Penny Whistle in the key of D

thingiverse

This whistle prints perfectly without needing extra help. Occasionally, some sanding is needed to make it fit right, so I smoothed it down and used beeswax on the joints for added stability. To tidy up inside the mouthpiece, an exacto knife comes in handy - simply insert it into any small openings you might see. For the tiny hairs that often form within the wind channel of the mouthpiece, a file is usually effective at cleaning them out efficiently.
