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