Telescope Helical Focuser
Description
I needed a cheap focuser for a telescope so that I could just test the mirror optics. Didn't want to spend money on a temporary focuser so I created this one. Has a flat mounting plate as my dobsonian has a flat attachment point for the focuser. Set screw for the eye piece can be whatever you can thread into it. There are no threads in the set screw location. Works a treat for me. Hope you it works for you too. Best to print it with no supports, as most slicers will try to support the threads and thats no necessary.
