Now I have come so far that I can start with making 3D CAD drawings for the pulleys I want to 3D print.
This is something new and I do a lot of mistakes, but still I have my first 3D printed puley and it looks to be usable.
First part of my documentation:

This is an sub part of my new setup for a 300 mm camera lens.
3D printing is amazing !
