Full refractor telescope

thingiverse

I designed this refractor telescope to fit a 63mm diameter lens with a 500mm focal length. Because of its size, the tube is divided into four main parts, each measuring 100mm in length. One part contains a dovetail for secure fixation. The focuser is specifically designed to accommodate 1.25" eyepieces. Later, I created an adapter to fit the focuser from ANicolai's design (http://www.thingiverse.com/thing:2130522), as the helicoidal focuser introduced unwanted vibrations, particularly at high magnification in the end_tube2 and porte_occ2 sections. I utilized part of Trevor Moseley's threading library (http://www.thingiverse.com/thing:27183) for this project. Print Settings: Printer: Tronxy X1 Rafts: None Supports: None Resolution: 0.2mm Infill: 20% Notes: I primarily used a 0.2mm layer height, except for the main tubes, where I increased it to 0.3mm for added stability. The key to successful printing is achieving perfect bed adhesion, either with or without rafts, to ensure that the parts assemble in a straight tube at the end. Support was necessary for the end part, which houses the focuser. Avoid using transparent or semi-transparent PLA, as it can cause residual light to reach the eyepiece, compromising image quality. I had to use blue PLA, which is semi-transparent, but this worked well enough.
