Skyglobe

The Skyglobe can show the locations of the sun and bright stars in the current sky, at any location on earth, any day of the year, and any time of the day quite accurately. You can use it to find out when and where the sun, a star, or a constellation rises and sets on a day, the location of them at a certain time of the day, or you can use it to know the location of the sun on the celestial sphere at a certain day of the year, or whether or not you'll be able to see a star at a certain location. You can watch a video of how to use it here You can watch a video of how to make it here It can be used by astronomy lovers to plan stargazing or locate stars and constellations, or for budding scientists to learn and get familiarized with the constellations and the movements of the sun at different locations and dates. The design is optimized for 3D printing, and requires no glue or screws. I did filament changes for the globes, horizon, meridian, and time wheels (only one extruder needed), and painted the stars according to the constellations. 20211026 Update: added a zip file containing photos of the star globe to show the details of the constellations (how I painted the stars). There is one top view of each hemisphere, and one at each quarter of the year (e.g. photo "N1" stands for northern hemisphere 1st quarter Jan - Mar). I tried to use different colors for nearby constellations (between yellow, blue, green, pink, orange), and if there's only one star in a constellation (when others are too dim to be included) I painted it grey.
