Doorbell Button Skulls

With only days to spare, I decorated the doorbell button:

Yeah, I jammed Sharpies in the eye sockets, but they look exactly the way they should. The middle skull is in the middle of the actuator in the hope that’s where it’ll get pushed.

The solid model comes directly from the seasonally appropriate teapot lid handle with a rectangle to suit the doorbell button actuator:

Perforce, the OpenSCAD code has eyeballometric magic numbers:

// Doorbell Button Enhancement
// Ed Nisley - KE4ZNU
// 2024-10-28

Button = [5.0,13.0,40.0];    // button width, boss depth, button height

union() {
    rotate([0,0,65])
    translate([-121,-105])      // totally eyeballometric
        import("stackofskulls - 50mm.obj",convexity=10);

        translate([0,Button.y/2,Button.z/2])
            cube(Button,center=true);
}

The rectangular slab goes all the way down to the platform because I couldn’t be bothered with support or a little wedge.

I’m sure it will survive exactly as long as it must.

Dunno how many little ones will venture up the driveway, though:
