Camera holder can be used for any Raspberry flat ribbon cable camera. It fits directly onto cheap 28BYJ-48 stepper motor shaft (4096 steps/rotation). Attached OpenSCAD file M5_3.scad allows you to change eg. vertical height, or make it tighter on stepper shaft (d=.04 means that in total 0.08mm space is between M5_3 and stepper motor shaft in any direction). This is a no_screw/no_glue model, tilt working with friction.

You can fixate stepper motor with shaft upwards best with clamp, or a bit of superglue.

M5_3 directly fits onto motor shaft, insert (4.9mm ⌀) flat_holder into its top (5.1mm ⌀) hole, then insert flat ribbon cable into flat holder and add camera. After camera is fixated on flat ribbon cable, best pull back as far as possible so that Raspberry camera touches flat holder.

Camera holder allows for manual tilt. Example code for controlling stepper motor and connection diagram can be found in this forum posting:
