Sexy-lovely, as usual. Had a question or two:
I was looking at your scad code, which is always enlightening (though i think i need to go redo classes in trig/geometry to understand it), but it seems to make references to "WriteScad" folder which isn't included. Is there a place to grab that?
Is there a particular reason to use PLA? I have a fear that a hotter bulb will warp or melt PLA (plus i just have more colors in ABS).
