<p>Note: 10/28/2020 replaced file "dfly tail.stl" with proper content. It previously had a duplicate of the file "dfly center body.stl".</p> <p>This is a dragon fly wind spinner with two six blade contrarotating fans. 608 style bearings are used for easy movement.</p> <p> <figure class="media"> <oembed url="https://youtu.be/ZfGworj5pe0"></oembed> </figure> </p> <p>Source files:<br/> <a href="https://www.tinkercad.com/things/3D1rz8MUDs8">https://www.tinkercad.com/things/3D1rz8MUDs8</a></p> <h3> Print Settings</h3> <p><strong>Printer Brand:</strong></p> <p>Creality</p> <p><p class="detail-setting printer"><strong>Printer: </strong> <div><p>Ender 3</p></div><strong>Rafts:</strong></p> <p>No</p> <p><p class="detail-setting supports"><strong>Supports: </strong> <div><p>Yes</p></div><strong>Resolution:</strong></p> <p>0.16</p> <p><p class="detail-setting infill"><strong>Infill: </strong> <div><p>15%</p></div><br/> <strong>Filament:</strong><br/> Polymaker Polyflex HT PLA+ Black <br/> <p class="detail-setting notes"><strong>Notes: </strong> </p><div><p> I used copper silk &amp; natural PLA+ for this print, liking the contrast between the metallic copper body and translucent wings.</p> <p>The complete model consists of one each of: head, center body, tail, ring A, ring B and stake mount; and twelve wings. I used PLA+ but that is not critical. The pictures should provide adequate information on how the body parts fit together.</p> <p>Head, tail and center body parts will need support (touching build plate only) when printing.</p> <p>You will probably need to do some light trimming on on parts to relieve edges where they fit together. Don't trim too much as you want a tight fit. The rings should fit on the 608 bearing as printed with a bit of pressure. If there is difficulty in fitting the bearing into the stake mount, a bit of heat to soften the plastic can allow for an easier insertion.</p> <p>Wings should fit into the rings tightly, but not so tightly as to cause the ring to split. Trim &amp; test fit to get the desired connection. Once complete you can consider using a small amount of super glue to insure the wings don't come out.</p> <p>My suggestion is to orient the wings on the rings so the "flatter" edge is toward the center. The wing mounting holes are oriented at a 35 degree angle. Rings A &amp; B are mirror images of each other and, in operation, their rotation should be in opposite directions.</p> <p>The stake mount is sized for use with 3/8" allthread rod.</p> <p>If the 608 bearings you acquire have heavy grease, I recommend soaking them in mineral spirits to help with removing it. Once the grease is out, lubricate with a light oil. This helps quite a bit in the ease of movement.</p> </div></p></p></p></p> Category: Outdoor &amp; Garden
