Non-rotary telescope focuser

thingiverse

This is a 3D design of a non rotary telescope focuser that I designed myself. (I got inspired by some of the designs shared here) What you will need: -40mm length M3 screw x3 for bearings (you might need to grind their sides on the end to prevent them touching mount plastic or try a little bit shorter screw) -20mm length M3 screw x4 for mounting -M3 nuts x16 or more -624zz bearings x6 50mm or a little bit shorter M6 screws and hexagonal rivet nuts (or inserts) x6 M5 screw x1 for locking the eyepiece Use nuts before and after bearings so they will rotate freely https://www.youtube.com/shorts/zualfJHQ3zE this is it in action
