Unsupported Angle / Overhang Tester, 5 - 90 degrees
thingiverse
This is a test piece I made to determine the amount of overhang I can use in designs without having to rely on supports. I was pretty impressed to see that I can get away with about 70 degrees of angle or archway! The part prints out in 5 to 90 degree slants in 5-degree increments. Level one is 5-45deg and should be no problem for any printer. Level 2 is 50-90deg... You will want to be present to abort the print when it starts to spray filament everywhere in the 90-degree stage :) See a sample video of this piece printing at http://www.youtube.com/watch?v=BXS56QR27Cs
