Designer Fruit Fly trap

prusaprinters

<p><a href="https://en.wikipedia.org/wiki/Drosophila">Drosophila</a> are annoying, so just put some small pieces of fruit (e.g. banana or apple) inside.&nbsp;</p><p>Don't waste time with mixing any attractant (sugar/vinegar/wine etc. )- They are made to find rotten fruit so this is the best way to attract them.&nbsp;</p><p>The big open area allow the scent to lure them with maximal efficiency and guide them to the center opening. But only 1% will find a way out again.&nbsp;</p><p>For ∅ 55mm bottle (top cut away) but the script is customizable with parameter.</p><p>If your bottle doesn't has a ring notch - carefully heat the rim so it will curve a little inward so later the prints protrusion can clip in. (e.g hold close over a hot (~150°C) plate)</p><h4>Print</h4><ul><li>Use vase mode / spiral mode</li><li>Bottom need to be 1.5mm so the fillet meet when the single wall starts</li></ul><p>&nbsp;The rim is reinforced (thicker) with a protrusion to clip into a bottle/glas notch.</p><p>You can also scale &nbsp;this for bigger diameter. (if you scale to much the flies will escape through the bigger slits)</p><p>example: &nbsp;for 64mm = &nbsp;64/55 = 1.164 = scale 116.4%</p>
