Making pulleys with a 3D printer

[Astrofriend]

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 !
