Description
No light source, hardware, or additional parts required. This fully 3D-printed globe demonstrates day/night cycles and seasonal changes, making it ideal for introductory geography lessons.
The model clearly illustrates the alternation of day and night due to the Earth's rotation.
Moving the lever on the right, which represents the sun's declination, the red arrow indicating this will change between 0°-23.5°, aligning with the true obliquity of the ecliptic. Simultaneously, the left side's night cover will reflect changes caused by the shifting sun's declination, creating the terminator. This visually demonstrates the polar day/night phenomena in the Arctic and Antarctic circles and the changing seasons. The numbers on the front scale represent dates, corresponding to the 24 solar terms, including spring equinox/summer solstice/autumn equinox/winter solstice.
The model includes a land and ocean globe. You can also substitute it with a different longitude and latitude globe or other earth models. Please ensure the earth's diameter is scaled to 50mm and the polar openings are 3mm in diameter.
I've only been using 3D printing for a few months and lacked prior experience; therefore, the model design may not be perfect. However, I've iteratively refined it through multiple print tests before uploading. Your support is greatly appreciated!
