Overhang Test Flower

thingiverse

I've been using this simple test print to compare various cooling duct designs. It gives you a clear view of part cooling and overhang ability at all angles, allowing you to judge their performance. Each petal goes through 60, 70, & 80 degree overhangs, providing a thorough evaluation. The smiley feature lets you see how fine features hold up and helps keep track of which side faced where during inspection. Printing time should be under 15 minutes, depending on your printer settings. I've attached some photos from a .1mm layer ABS print to give you a better idea of the results.
