Sony E-Mount 1.25" Telescope Adapter

Single-piece adapter for mounting a Sony E-Mount camera to a 1.25" tube.

Thanks to this model/designer for the e-mount geometry.

Designed for and tested with a Sony a6000 and Celestron NexStar 5SE, but should work with most E-Mount cameras and telescopes with 1.25" optics.

Tips/Settings:

• PETG recommended, though I'm sure PLA would work fine
• Take advantage of variable layer heights to reduce print time (e.g. the main tube is just a plain cylinder, which can use a larger layer height. But the fitting should be as precise as possible)
• Print with the tube face down (as positioned in the file)
• Supports should not be needed
• Use ironing to make the surfaces that mate against the camera as smooth as possible. And/or sand it to a smooth finish
• Post-processing: Be sure to thoroughly clean up any stringing, dangling bits of filament, etc. You don't want little pieces of plastic getting into your camera or telescope optics

See gcode/3mf for my print settings. I used black PETG Prusament.
