In these rainy days I thought a lot about my focuser. The original friction focuser which is very good when only attaching low weight oculars but doesn't work very good with heavy loads as a camera. It will never work as good as I wanted it to do whatever I try to do with it. Now I try to rebuild it with a rack & pinion construction, and more, I try to 3D-print the parts.
Have a look on my first prototype gears:

This is very exiting if I can use the 3D-Printer to make this rack & pinion mechanics.
The 3D-Printer is my best friend !
