This tutorial revisits a parametric 3D printable panel that I created a while ago using plain Ruby code. You can explore the original 3D model using the viewer below. Just click the image to start it.
Since the underlying code is now included in my Scale By Tools extension, I used it to re-create the same panel. Watch the video to see how you can very easily create the same design (or whatever else you want) with it. You can then 3D print it, laser cut, CNC cut, or use a waterjet cutter to create this panel out of many materials.
