OpenSCAD Bevelled Text

thingiverse

I needed to 3D print a key tag featuring someone's initials. I discovered that creating extruded text with square edges in OpenSCAD is straightforward but I wanted beveled edges, which turned out to be more challenging than expected. So this "thing" demonstrates the technique I came up with. The idea is to gradually increase the 'linear_extrude()' as the 'offset()' is progressively decreased. I attempted to use a 'hull()' between each subsequent layer but that failed because 'hull()' also fills in the insides of the letters, which was not desired. Warning: This code renders very slowly in OpenSCAD when preparing to export an STL file. Fortunately, just redrawing on screen is relatively fast.
