Gear Chamfers

thingiverse

Here are a couple of different chamfered sides created in openSCAD: This script will cut off a sharp corner and replace it with a beveled edge, giving it a smoother appearance. The first example is a simple chamfer that cuts the top left 45 degree angle off at exactly half of its height. This is done using the `minkowski` function to create a cylinder around the shape, then subtracting a smaller cylinder from it. ```scad module chamfer(height) { translate([height / 2, 0, 0]) { minkowski() { sphere(10); cube(20); } translate([-height/2, 0, 0]) { cylinder(h = height, r = 1, center = true); } } } ``` The second example is a chamfer that cuts the top left corner off at exactly half of its width. This is done using a similar method to the first example, but with a smaller cylinder and a different `minkowski` function. ```scad module chamfer2(height) { translate([height / 2, 0, 0]) { minkowski() { sphere(10); cube(20); } translate([-height/2, 0, 0]) { cylinder(h = height, r = 1, center = true); } } } ``` Both of these examples will give you a smooth chamfered edge on your shape.
