I could not find one so i made one, done on DesignSpark, replaces the original Meade view finder mount, same alignment notch, just screw it on and slide the Red Dot Pinty or alike) on it. Print upright with some tree support for the separated dovetails. These are aligned with locking block ans screw on some red-dot devices. I did infill 100% for maximum strength but 25 to 50% goes a long way too.
