In this OpenSCAD tutorial series we’ve covered the basics of the OpenSCAD interface, how to make 2D forms, how to make some basic 3D forms, how to position those forms in 3D space, the different ways to combine forms, how to create mashups of one or more existing STL’s and OpenSCAD forms, how to use modules to reuse your code to make your life easier, how to extrude flat 2D forms into 3D forms, and how to fix design problems.  Although I described a few of the last tutorials as “intermediate” levels, that’s really only because you learned the basics so quickly from the first few tutorials.

Today I’d like to show you how easy it is to make some neat organic looking forms with OpenSCAD.  The secret behind doing so are two functions, “hull” and “minkowski.”  Let’s learn a little bit about what each of these functions do and try out some code.  More, after the break!
