Overhang torture test.

thingiverse

How effectively does your printer handle an overhang? This print demonstrates just how far your printer and settings can accommodate an overhang before the print begins to distort and turn into a tangled mess. Each arc increases by 10 degrees from 0 to 90, proving that printing at an angle is not always feasible, especially when it comes to preventing sagging or collapse. Note: Printing on its side is essentially cheating and defeats the purpose of this test.
