Window Opener

To automate the opening and closing of my bedroom windows and curtains is a wish since I was 12. Now with al the technics at hand it had to become to realization. For the first version it has to be simple and this can be done with a rack&pinion. I found some standard parts, changed them to my needs and send them to the printer. At the same time other parts are drawn. For me the ultimate form of engineering: idea – solutions – reality.
