Overhang test for RepRap/RapMan/RepStrap

thingiverse

This 3D-printable test object showcases a range of overhang angles for assessment. Angles in descending order are 90°, 80°, 90°, 70°, 90°, 60°, 90°, 180°, 90°, 55°, 90°, 50°, 90°, 45°, 90°, 40°, 90°, 35°, and 90°. The bottom part features angles of 80°, 70°, and 60° that should print on any machine. The top section comprises angles from 55° to 30° in 5° steps for evaluating preferred overhang angles or determining unprintable ones. Additionally, a flat overhang test (test_overhang_flat.stl) has been added, with one side featuring 60°, 55°, 50°, and 45° angles, and the other side showcasing 40°, 35°, 30°, 25°, and 20° angles, both with 90° intervals. The object should be printed without support, and a separate "TOP" part is also available for printing if desired, showcasing problematic overhangs below 60°.
