Remix of Inertpyro' awesome aperture door, 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.
Inspired by DaBen I also made a inlet to prevent the fans blowing directly on the printer.
-Door blade and the gears are the same as found on the original versions.
-Baseplate and topside tube are remixed.
-1x Mini servo, I used the same as AcE_Krystal - https://tinyurl.com/yy9of9qh

-Circle compass and a Jig saw, or use a 114mm (4 1/2") hole saw with the drill
-Various screw drivers
-Wood file or sawblade (i.e from a coping saw or similar)
-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.
-Use the printed topside_tube as a template for marking out the servo and screw holes.
-Drill the four holes with a 5mm bit.
-I drilled two 10mm holes carefully aligned where the servo motor goes, and used a wooden file to make the hole square.
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.
