About this 3D model

This is a module that uses the OpenSCAD minkowski() function to allow you to extrude an arbitrary 2D shape with a bevelled edge on top. If you have concave corners, then you may want to specify a number of facets on the curved bevel that is created using the $fn= argument. It is a bit slow because OpenSCAD's minkowski seems to take a while. The arguments are: * height (How high the 2d shape is extruded). * bevel_depth (How low the bevel is cut into the top of the extruded object). * $fn = (number of facets on curved bevels of concave corners).
