Sextant MK2

thingiverse

This is the second version of my Sextant, an instrument that sailors use to calculate their latitude by measuring the angle between the Sun or other stars and the horizon. A fixed scale is included but I haven't had a chance to verify its accuracy, so if it's incorrect please print one yourself using this guide: http://www.tecepe.com.br/nav/XTantProject.htm. To assemble the Sextant, use M3 screws to secure the handle, then simply snap the pointer into place. Alternatively, you can use glue, but ensure that the parts requiring movement remain free to move. You'll also need two 40 x 12 mm mirrors, preferably made of polished metal without glass to prevent refraction. Changes in the Sextant MK2 include: - A slightly larger frame - The lower mirror and sights are now fixed in place - The pointer is designed to snap into position easily - The scale is engraved directly onto the main frame, eliminating the risk of collision with the pointer.
