Fruitfly trap lid

prusaprinters

<p>Note August 2020: Turns out my mason jars were 'wide mouth'. So I've finally designed some for what I take to be 'standard' sized. Pictures coming.</p> <p>Designed to screw on the top of a mason jar with a ring/collar screw top thing. I happened to have these 1-cup (250ml) jars hanging around.</p> <p>Fill the jar about half way with just a drop of dish soap, and a mixture of about half vinegar and half water. (Apple cider vinegar is recommended, but I've tried others and they work fine. Actually, you can use it full strength; I just was running low and got cheap.) Put the lid (cones pointing in/down) over the mouth of the jar and secure with the ring. Leave wherever your fruitflies seem to be. You will be amazed.</p> <p>The theory: Vinegar attracts the fruitflies, the conical shape of the lid-holes make it easier for them to get in than to get out. The dish soap reduces the surface tension of the vinegar/water so when they touch down the fruitflies drown.</p> <p>I've added a chunk of dying watermelon I dropped on the floor to one. They really seem to like it. In the past I've used a slurry of flour and yeast, worked but not as effective. Vinegar all the way.</p> <h3>Print Settings</h3> <p><strong>Printer Brand:</strong></p> <p>Anycubic</p> <p class="detail-setting printer"><strong>Printer: </strong> <div><p>All-metal Mega</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>0.2mm layer height</p> <p class="detail-setting infill"><strong>Infill: </strong> <div><p>100%*</p></div> <p><strong>Notes:</strong></p> <ul> <li>The thing is only 1mm thick, so at typical settings there won't be any infill needed.</li> </ul> </p></p></p> Category: Household
