This is a very affordable 3D printed post holder for mounting 10mm diameter optical posts.
To fix the post height simply tighten the M6 set screw in one of the four M6 threaded holes on the side. The built-in clamp gives a 60mm diameter positioning circle for the user.
Inner diameter: 10mm
The pots holder can be mounted in two different ways to the optical table. Using the M6 screw on the clamp side or with a M6 screw inside the base.
