Servo automated iris / aperture for air flow controll IKEA Platsa

prusaprinters

<p>Remix of Inertpyro' awesome aperture door (<a href="https://www.thingiverse.com/thing:529661">https://www.thingiverse.com/thing:529661</a>), combined with AcE_Krystal' genius servo driven open/close function to fit 120mm fans in Ikea Platsa enclosure. Or any other 18mm (3/4") thick plates.</p> <p>Inspired by DaBen (<a href="https://www.thingiverse.com/thing:3697275">https://www.thingiverse.com/thing:3697275</a>) I also made a inlet to prevent the fans blowing directly on the printer.</p> <p>-Door blade and the gears are the same as found on the original versions.<br/> -Baseplate and topside tube are remixed.</p> <p>Hardware list:</p> <p>-1x Mini servo, I used the same as AcE_Krystal - <a href="https://tinyurl.com/yy9of9qh">https://tinyurl.com/yy9of9qh</a><br/> -5x M3x6mm cap head screws - <a href="https://tinyurl.com/y67j3l76">https://tinyurl.com/y67j3l76</a><br/> -5x M3x9mm washers (larger OD than standard) - <a href="https://tinyurl.com/y5pvbbtl">https://tinyurl.com/y5pvbbtl</a><br/> -2x M2x10mm countersunk screws, washers and nuts - <a href="https://tinyurl.com/y2txvgz5">https://tinyurl.com/y2txvgz5</a><br/> -4x M4x60 countersunk screws and nuts - <a href="https://tinyurl.com/y267gsuc">https://tinyurl.com/y267gsuc</a><br/> -1x M5x10 countersunk screw for the inlet lid - <a href="https://tinyurl.com/yxzn7rbf">https://tinyurl.com/yxzn7rbf</a></p> <p>Tools:</p> <p>-Drill<br/> -Circle compass and a Jig saw, or use a 114mm (4 1/2") hole saw with the drill<br/> -Various screw drivers<br/> -10mm drillbit<br/> -5mm drillbit<br/> -Wood file or sawblade (i.e from a coping saw or similar)<br/> -Vacuum cleaner</p> <p>-For installment you need to find the center where you want the fan, cut out a 114mm (4 1/2") hole with a hole saw. Or use a compass to draw a circle and use a normal jig saw.</p> <p>-Use the printed topside_tube as a template for marking out the servo and screw holes.</p> <p>-Drill the four holes with a 5mm bit.</p> <p>-I drilled two 10mm holes carefully aligned where the servo motor goes, and used a wooden file to make the hole square.</p> <p>Fire up the vacuum cleaner, and now you are all set for having one or several cool looking fan apertures. Maybe you are also like me; time to learn Arduino from scratch.</p> <h3>Print instructions</h3><p>PETG<br/> 0.2mm layer height<br/> 20% infill</p>
