OpenSCAD squircle

OpenSCAD squircle

The amount of slightly different squircle implementations in my different OpenSCAD projects was getting too damn high, so here's a pretty robust one.

Installation

Add a git submodule to your project:

git submodule add https://github.com/mmalecki/openscad-squircle squircle

Usage

use <squircle/squircle.scad>;

// Simple usage:
squircle([20, 25], 1, center = true);

// A bit more fancy:
translate([30, 0])
  squircle([20, 25], [0, 5, 7.5, 10], center = true);

API

squricle(size, r, center = false)

Draws a 2D squircle.

Arguments:

• size - size of the base square
• r (number, list of 4 numbers) - the radius or radii of the corner circles (0 for no corner circle)
• center (boolean) - whether to center the squircle
