Don't just jump in here, start from Part 1! Now it's time for the big finish. For our final decorative flourish, we're going to put a large rounded corner on each of the three surfaces with screw holes in them, with the radius of the corner determined by how close the screw hole is to the edge.

And by the way, if you know a little something Read more [...]

A fillet is essentially a curved edge. As far as OpenSCAD is concerned, it's helpful to think of creating this curved edge by subtracting from our object one Read more [...]
