Round corners for Openscad - Tutorial

thingiverse

Uncovering hidden treasures in OpenSCAD, a tutorial on creating rounded corners using 'hull()' function demonstrates various ways to design boxes. The 'boxes.scad' included with OpenSCad shows that there are more techniques for box creation. In a rounded rectangle example, 'hull()' fills a convex hull based on 2D points by placing circles at corners and linear_extruding height. Flexibility is key as this method can be applied to any shape with multiple circles. Another approach using minkowski sum is shown in the 'miniround' module, where a cube and cylinder are combined to create rounded corners. Using $fn=12 allows sphere use for 360-degree rounded corners, but higher values increase rendering time. The 'roundedPolygon' example highlights OpenSCad limitations with minkowski usage. Despite numerous libraries available, exploring possibilities may lead to discovering alternative methods better suited to specific needs and situations. So, download the .scad file, play around, and enjoy the journey of OpenSCad discovery!
