This is an eight-leaf overhang torture test, with overhang angles from 40 to 80 degrees in 5 degree steps. Each angle section is labeled on both sides for readability. The base of the model is labeled to help identify the original print orientation. The overhangs are supported by ribs to help reduce movement during printing.
This print is designed to be very challenging and difficult to print, to highlight the effectiveness or otherwise of your part cooling fan setup - it is normal for the steepest overhangs to print somewhat poorly even with really good cooling.
For a 0.4mm nozzle, I print this at 0.2mm layer height, 40% infill, 4/5/5 perimeters, but the exact settings likely don't matter much. Just make sure your fan is running at 100% for most of the print, especially on the overhangs.
