wind spinner v3

prusaprinters

<p>A wind spinner sized for Ender 3 or similar, this is an update to an earlier design &amp; incorporates elements used in the large V5 spinner ( <a href="https://www.prusaprinters.org/prints/96490-wind-spinner-v5">https://www.prusaprinters.org/prints/96490-wind-spinner-v5</a> ).</p><p>The sail blade attachments are much more sturdy than the original six blade windmill design and are held in place through the blade root with 3mm cap head screws (12 - 14mm) and nuts. Those screws also join the two part hub.</p><p>There are two hub categories which enclose either one (SB) or two (DB) 608RS bearings. A two bearing hub can be more stable and allow a closer fit at the expense of a bit more drag. Axle shafts consist of 5/16" bolts for both horizontal &amp; vertical axes. Alignment jigs are available to assist in getting a right angle position established while gluing the axle bolts in place.</p><p>The stake mount uses two bearings (DB) for a more stable upright posture for the assembled spinner.</p><p>The overall design supports either a single or double fan arrangement, with two hub/blade versions (A &amp; B) having opposite blade orientations to permit contra-rotating fans. Spacers maintain clearances between nose, base and hub components.</p><p>There are two versions of the "base" part (the part that sits on the stake mount &amp; holds the tail and forward parts). The "short base" is appropriate for a single fan spinner. The "long base" would be appropriate for a double fan spinner adding more leverage &amp; counterweight to the rear of the assembly.</p><h3>Print Settings</h3><p><strong>Printer Brand:</strong></p><p>Creality</p><p> </p><p><strong>Printer: </strong></p><p>Ender 3</p><p><strong>Rafts:</strong></p><p> </p><p>No</p><p> </p><p><strong>Supports: </strong></p><p>No</p><p><strong>Resolution:</strong></p><p> </p><p>220</p><p> </p><p><strong>Infill: </strong></p><p>15</p><p><br/><strong>Filament:</strong><br/><br/>any PETG <br/> </p><p><strong>Notes: </strong></p><p>Using a concentric pattern for the top layers makes for interesting patterns on the blades and tail when printing with a translucent material.</p><p>I have been printing with PETG &amp; 0.24mm layers. Finer resolution will increase the number of "steps" on the printed tapered sail blades.</p><p>My experiences are that PLA will not stand up to extended outdoor exposure. I saw sun fade, sag and deterioration.</p><p> </p><p>If printed items appear too tight, you may need to tune your flow rate.</p><p>If printing the nose bolt alignment tool, scale up by 5% (i.e. print at 105%) for an easy fit with a 5/16" bolt.</p><h3>Post-Printing</h3><p><strong>Assembly</strong></p><p>The A &amp; B designations are for wing/hub assembly. A blades on type A hub, B blades on a type B hub. Wing roots and hub openings are keyed for one way orientation during assembly. 3mm cap head screws (12 - 14mm long) are used for hub assembly &amp; tail attachment.</p><p>You may want to clear the printed screw holes with a tool or drill to ease assembly. Nuts &amp; bearings may need to be pressed into place with a clamp or pliers during hub assembly. The tail can be secured to the base with a 3mm screw or CA glue.</p><p>5/16" bolts are used as axle shafts. You can tighten fitment of the bolt in the bearing by shimming the bolt shaft with a bit of aluminum tape. CA glue was used to attach bolt heads to the nose &amp; base pieces. The bolt alignment tools can help with getting the right orientation. The opening in the tool may need to be cleaned up with a drill for easy movement of the tool on the bolt. A spacers with a hex shape can be glued over the bolt head for more security to the glued fit.</p><p>The axle bolt glued to the nose will get screwed into the base used. Pre-threading the base with a loose bolt can ease final assembly. I used a1 1/2" bolt for the vertical axis into the double bearing stake mount, a 2" bolt as the horizontal axle for a single fan build and a 2 1/2" bolt for a double fan build.</p><p>The stake mount is sized to fit on a 3/8" all-thread rod.</p><h3>How I Designed This</h3><p>This was done in Tinkercad.</p><p>Components can be found here:</p><p><a href="https://www.tinkercad.com/things/c5Bw11BEyo5">https://www.tinkercad.com/things/c5Bw11BEyo5</a></p><p> </p><p> </p><p> </p><p>Category: Outdoor &amp; Garden</p>
