birb_chirper

prusaprinters

<p>This is one of those toys that you whirl around on a piece of string and it makes a chirping sound like a flock of sparrows. I have no idea what they're called, so I called it birb_chirper.</p> <p>If you print this at 200% and whirl it from a length of paracord, it sounds like a tremendously vexed seagull.</p> <p>Design has been updated for smoother corners.</p> <h3>Print Settings</h3> <p><strong>Printer Brand:</strong></p> <p>Prusa</p> <p class="detail-setting printer"><strong>Printer: </strong> <div><p>I3 MK3S</p></div> <p><strong>Rafts:</strong></p> <p>No</p> <p class="detail-setting supports"><strong>Supports: </strong> <div><p>No</p></div> <p><strong>Resolution:</strong></p> <p>0.2</p> <p class="detail-setting infill"><strong>Infill: </strong> <div><p>0%</p></div> <p><strong>Filament:</strong> Generic PET-G Green</p> <p><br/> <p class="detail-setting notes"><strong>Notes: </strong></p> </p><div><p>This is a thin-walled model, so use at least two shells and no infill for smooth walls.</p></div> Post-Printing ============= <p>Take a piece of thin string about 1 metre long (I used micro-cord, very fine paracord), pass it through the hole in the tip, then tie off a jam knot that's big enough to stop in the hole in the top but still pass back through the slot in the side. Now whirl the thing around fast by the string, and it should start to chirp.</p> <p>The big version needs full-size paracord and is immensely annoying!</p> <p>This is intended for the amusement of small children and the annoyance of adults.</p> <h3>How I Designed This</h3> <p>The tip of this thing is an ogee curve. I've included my library for creating simple ogee and ogive profiles.</p> </p></p></p> Category: Other
