OpenSCAD Tools

OpenSCAD is a free, code-based CAD tool: you describe a solid model with a short script, and changing a number regenerates the part. That makes it well suited to parametric parts for 3D printing, laser cutting, and customizable designs.

New to OpenSCAD? Follow the interactive six-lesson beginner tutorial: edit each exercise, render it in 3D, and check your answer, all locally in your browser. Then practice with guided examples and keep the cheatsheet open while you work.

Common OpenSCAD patterns

Three building blocks behind most models. See the OpenSCAD cheatsheet for more.

Drill a hole with difference()

difference() {
  cube([40, 30, 5]);
  translate([20, 15, -1]) cylinder(h = 7, d = 8, $fn = 48);
}

Reusable part with a module

module peg(h = 10, d = 6) cylinder(h = h, d = d, $fn = 32);
for (x = [0 : 10 : 40]) translate([x, 0, 0]) peg(h = 5 + x / 4);

Extrude a 2D profile

linear_extrude(height = 10)
  offset(r = 3) square([30, 20]);
