ZWO EAF Fast Coupler for Celestron C8/C9.25 SCT

thingiverse

I didn't want to attach my ZWO EAF to my C9.25 permanently, as this makes it harder to transport and cumbersome to use visually. I designed the holder in a way that only a small base part is attached permanently and does not hinder using the standard focuser knob. If needed, the EAF is then attached by simply plugging it onto the focuser knob and tightening a union nut grabbing the base part. No additional screws/pulleys/belts are required.
