Playing with LEGO and servos

Playing with OpenSCAD, LEGOS and a servo

I've been playing with an idea, to design a simple LEGO part to attach a standard servo. Here's the pic.

I'm using a https://github.com/cfinke/LEGO.scad[LEGO.scad]] (underfull library) and MCAD for the servo model.

Look great!

Here's the OpenSCAD code:

        difference(){

        place(3, 0,2)
        rotate([0,90,0]){
            poly_cylinder(h=50,r=1.5,center=true);}

        translate([0,0,10]){
            place(3, 0,2) {
                rotate([0,90,0]){
                    poly_cylinder(h=50,r=1.5,center=true);}}}}}

Looks great doesn't it?

Happy hacking!
