Full refractor telescope

I designed this refractor telescope to fit a 63mm diameter, 500mm focal length lens. Because of the size, the tube is divided into 4 main 100mm parts, with one of them containing a dovetail for fixation. The focuser is made for 1.25" eyepieces. I later made an adapter to fit the focuser from ANicolai: http://www.thingiverse.com/thing:2130522, because the helicoidal focuser introduced to many virbations, especially at high magnification (end_tube2 and porte_occ2.

I used part of the threading library from Trevor Moseley (http://www.thingiverse.com/thing:27183).
