Helix WindMill

thingiverse

I've used a high-performance ABEC7 bearing for the rollers in line. Allowing the bearing to soak in mineral oil for some time helps achieve a smooth and faster turning.\r\n\r\nFor the Helix design, I relied on Openscad. As it's my first design, please don't judge me too harshly.\r\n\r\nThe linear extrusion code reads: linear_extrude(height = 120, slices = 100, center = false, convexity = 10, twist = 130, $fn = 100){\r\ndifference() {\r\ndifference() {translate([-20,0])circle(20, $fn=100);translate([-20,0])circle(19.5, $fn=100);}\r\n;{translate([-40,0])square(200)\r\n;}\r\n;}\r\n}\r\nlinear_extrude(height = 120, slices = 100, center = false, convexity = 10, twist = 130, $fn = 100){\r\n\r\ndifference() {\r\ndifference() {translate([19.5,0])circle(20, $fn=100);translate([19.5,0])circle(19.5, $fn=100);}\r\n;{translate([-0.5,-40])square(40)\r\n;}\r\n;}\r\n}
