This an 80mm objective diameter, 330mm focal length refractor telescope. It is a work in progress, but it should be functional as-is with some fuss and fitting. each section is small enough to be printed on a Prusa Mini. It uses this 1.25" crawford focuser and a cheap lens off I got off ebay. Additionally a 1.25" diagonal and eyepieces are required to make this functional.The lens is 82mm is diameter and I measured its focal length at 316mm. I do get some chromatic aberrations as is typical with lens of this type. Overall this is a cheap and relatively fast scope with reasonable image quality.So far I have only printed this in PLA, and I will report back if I have any issues. A variety of M3 and M4 screws and threaded inserts are also required for assembly. Additionally one ¼ 20 threaded insert is required for the tripod mount. Four springs are needed for the lens cap. Update 7/19/2022: so far the PLA has held up fine. It survived a week long RV trip being bounced around on dirt roads.
