This is a camera / webcam mount that fits on my printer's Z-axis. It fits on the two screws that hold the outside wheels. These are separated by 66mm on my printer. If yours is different, you may need to adjust the spacing in the scad file before regenerating the stl file.
It still allows use of the X belt tension adjustment.
It moves up and down with the top of the model, which allows nice timelapses to be captured.
Can be printed without supports.
The author marked this model as their own original creation.
