I made this to illustrate a point for a project I'm working on about modeling for 3D printers. The rule is that 3D printers can handle gradual overhangs but do not go over 45 degrees or you'll have trouble. So I made some overhangs at 30, 45, and 60 degrees and printed them out.
The success of this has to do with a lot of factors not the least of which being how much the overhang has to hold on to. So if this had been a 60 degree incline in all directions it likely would have had the desired effect, but either way I can't use this illustration for that project any more.
