This simple model is designed to test the maximum overhang that your 3D printer can handle. The angles from top to bottom are as follows:

  • 90°
  • 80°
  • 90°
  • 70°
  • 90°
  • 60°
  • 90°
  • 180°
  • 90°
  • 55°
  • 90°
  • 50°
  • 90°
  • 45°
  • 90°
  • 40°
  • 90°
  • 35°
  • 90°
  • 30°
  • 90°

In summary, the lower section of the model includes angles of 80°, 70°, and 60°, which should work for most machines. The upper section ranges from 55° to 30° in 5° increments, allowing you to identify which overhang angles your printer can handle effectively and which ones are not printable.

EDIT:
I've also added a overhangfile, as feedback suggested that overhang performance differs between round and flat surfaces. This new file is designed to test the flat overhang.

One side (right) has angles of 60°, 55°, 50°, and 45° (with 90° between each), while the other side (left) has angles of 40°, 35°, 30°, 25°, and 20° (again, with 90° between each).

Instructions:

  1. Print the model without supports.
  2. There is also an file containing only the top part of the model, which is more problematic if overhangs are below 60°. You can use this if you only want to print the challenging section, knowing your machine performs well with angles up to 60°.
