(parametric) Ventilation cover [circle]

I present you a parametric model that allows you to create your own ventilation cover. The idea is that the cover sits flush with a wall or surface. Parameters: Diameter: diameter of the inner circleThickness of the border: border thickness which is added to the diameterSpacing grid: spacing between finsThickness grid: thickness of a finAngle grid: angle of a fin. Put 90 degree if you want to angleQuantity of fins: quantity of fins. So you can match it to your likingDepth: depth of the extrudeBorder radius: border radius of the outer squareChamfer: chamfer of the outer squareDrill hole diameter: diameter of the drill holeDrill hole chamfer: chamfer of the drill hole No support needed and attached print profile has a default model which some settings enabled. So you can easily drop your created stl in it and start printing! I've also created one for a square design. (click image) If feedback, please let me know! I'm always trying to improve my designs.
