The author remixed this model.
This model distinguishes itself from its source model in that it replaces the ball joints with a lightweight rigid arm with printed bolts that can be tightened. These changes help to limit undesirable shifting overtime of the camera's position and angle as it travels along with the x-axis during prints.
Additionally, the arm's attachment has been moved lower so that it can be automatically positioned at an appropriate angle to the bottom of the hotend. The camera shell and lid have been thinned out to both decrease weight and enable additional space for thicker raspberry pi cameras.
If printing at the right orientations, supports may only be needed for the camera_shell.stl
Note: Also works with Ender-3 S1.
