OpenSCAD as sex toy generator

balls_scadOpenSCAD is a free software tool for creating 3d objects. But it is different from other CAD tools like Tinkercad or Freecad. Instead of using the mouse to select and modify 3d objects you have to use a description language. Making a 3d object in OpenSCAD is a bit like programming. For creating a sphere you just have to type sphere(r=10); where r is the radius of the sphere. For creating a cube or a cylinder just type in the appropriate command. When done select compile from the menu and you’re object will be displayed.

Just download the OpenSCAD software, install the tool and try out a command. You can copy and paste the dildo generator source code (at the end of this blog post) and try to change the parameters. Another option is to use the customizer module of the Thingiverse platform.

Brief Intro to OpenSCAD

openscadintro If you want to create a sphere not in the origin but somewhere else you have to shift the object using the translate command. For creating the second smaller sphere use

translate([30,0,0]) sphere(r=10);

The translate command moves the sphere objects on the x-axis by 30 points.

To visualize the form use the design menu and select “compile” or “compile and render”. Rendering takes some time (up to some minutes) but it will give you a correct preview of your form.

To build more complex objects you have to use the union or difference command. The union command puts simple objects together. With the difference command you can cut out something e.g. to make a ring. openscadintro2 You can download a STL-file (select “export STL” from the menu) and print out the form with a 3d printer.

OpenScad can be used to create sex toys as shown by Mr O. He used OpenScad to create basic building blocks for sex toys which can be combined and changed in size. Moreover with OpenScad you can make generative designs. For example you can make a generative dildo which can be individualized by changing parameters like height, length etc.

Generative Dildo Project

Let us create the “balls” dildo which is introduced in Silicone overmolded vibrator – balls revisited and Update for “balls revisted” – silicone molded vibrator.

molded-querThe dildo consists of 6 forms:

  • three spheres with individual radius
  • a base which is made of cylinders
  • and an iterative use of circles to make the upper top of the base to be round

We use the module command to encapsulate the commands for creating the dildo. A module is very similar to functions or procedures in other programming languages, but they do not return a value. They just execute the commands in the module. The definition of the module starts with its parameters.

module base (r_bottom,height,rounding,connector_radius,ball_distance, c1,c2,c3) {
  ...commands for creating the dildo...

c1, c2 and c3 are the radius of the spheres. r_bottom is the radius of the base part and height the height if the base parts.


Now you can produce different versions of the ball motive by entering different parameters when you call the module base. With the following parameters the form at the left side will be generated:




ball_scad_alt_parametersThis form will be made when using the following parameters:





Make your own generative sex toy design and publish it

The Thingiverse platform is able to create objects made with OpenSCAD. Just upload the SCAD-file to Thingiverse using the customizer option. Now you can change the parameters within Thingiverse and generate a customized STL-file for 3d printing. Try it out with the Thingiverse customizer (as long as nobody complains…).

Download the SCAD file source code here: form_only

Or copy & paste the following SCAD code to generate the “balls” sex toy:

// bodyinteraction toy form

// radius of bottom part
r_bottom=50; // [50:5:80] 
// height of bottom part
h_bottom=60; // [10:5:80] 
// top rounding of bottom part
rounding=10; // [10:5:20]
// radius of ball 1 
r_ball1=35; // [15:5:50] 
// radius of ball 2
r_ball2=25; // [15:5:50] 
//radius of ball 3 
r_ball3=20; // [15:5:50] 
// radius of connecting cylinders
connector_radius=10; // [10:2:20]
// distance between balls and bottom part
ball_distance=30; // [10:2:40]


module base (r_bottom,height,rounding,connector_radius,ball_distance, c1,c2,c3) {
 union () {
 // connector
 color("DarkSlateBlue") cylinder (h=height-0,r=r_bottom-rounding,$fn=60);
 color("MediumSlateBlue")cylinder (h=height-rounding,r=r_bottom,$fn=60);
 translate([0,0,height-rounding]) color("SlateBlue") rotate_extrude() 
 translate([r_bottom-rounding,0,0]) circle(r=rounding,$fn=120);
 // circle (ball) 1, 2 and 3
 translate([0,0,height+ball_distance+c1]) color("Indigo")sphere(r=c1,center=true,$fn=60);
 translate([0,0,height+2*ball_distance+2*c1+c2]) color("Violet")sphere(r=c2,center=true,$fn=60);
 translate([0,0,height+3*ball_distance+2*c1+2*c2+c3]) color("Purple")sphere(r=c3,center=true,$fn=60);
