Human: Original Source under: https://github.com/rmd6502/openscad/blob/master/pinwheel.scad\r\nIt's great! Thank you rmd6502.\r\n\r\nFinally a Windrad for Openscad. Thanks.\r\n\r\nIt's a small script:\r\n\r\nsides = 3;\r\nangle = 360 / sides;\r\nradius = 100;\r\nrotate([0, 0, $t*angle]) union() {\r\n difference() {\r\n union() {\r\n linear_extrude(10, scale=.525,twist=-22,slices=40) for (rot = [0 : angle : 359])\r\n rotate(rot) translate([0,-1.5,0]) square([radius,3],center=false);\r\n cylinder(h=10,r1=radius/8.5,r2=radius/30,$fn=50);\r\n }\r\n cylinder(h=8,r=2,$fn=20);\r\n difference() {\r\n cylinder(r=radius+.5,h=10,slices=50);\r\n cylinder(r=radius*.85,h=10, slices=50);\r\n }\r\n }\r\n// translate([0,0,1.5]) rotate_extrude($fn=90) translate([radius*.85,0,0]) //circle(r=1.5,center=true,$fn=40);\r\n}\r\n//that's all
