Rounded and filleted prisms in OpenSCAD

thingiverse

OpenSCAD is an excellent tool, but its rounding capabilities tend to be sluggish, and creating fillets to join parts can be a snail's pace. In the past, I've relied on a general-purpose library, which, although impressive, was astonishingly slow. This script leverages OpenSCAD as a 3D library and largely disregards (though not entirely) its CSG aspect to craft shapes that prove challenging with OpenSCAD primitives alone. The skin() module from list_comprehensions is utilized here, but it necessitates certain components being dropped from the current scad_utils. Consequently, I've brought skin() and what it requires into my source code directly. 2019-02-27: The script has been updated to include more options, fewer bugs, increased control over smoothing, and even documentation within the source itself. 2019-03-07: Several bugs have been fixed regarding chamfer mode (and the value of $fn adjusted to facilitate this) as well as ysize functioning correctly in all (or perhaps most) instances.
