Description
This mini globe with meridians and parallels in relief, along with the Moon at the same scale as Earth, can be used as a decorative ornament or an educational tool to explore a variety of concepts. By using a flashlight or small lamp, students or kids can learn about the phases of the moon, the cycle of day and night, and the changing seasons. It also helps illustrate the Arctic seasons, solar insolation at different latitudes, and the mechanics of solar and lunar eclipses. This hands-on approach offers a visual and interactive way to understand Earth's movements and their effects.
The entire model consists of 4 pieces:
The model is at a scale of 1 : 127,420,000 to actual size.
The globe is a sphere with a diameter of 10 cm and the stand is inclined at 23.45°, reflecting the Earth's rotational axis. The base is a circle 10 cm in diameter and the model is a total of 17.5 cm high.
To reflect the Earth-Moon distance, the moon should be placed 301.64 cm (118.74 inches) away.
Earth-Moon distance: 384,400 km (238,855 miles)
NOTE: The model can be enlarged by upscaling all pieces of the same factor in the slicer before printing to suit your needs, however, the tolerances of the parts could be excessive if enlarged and no longer optimal.
This elegant 3D printed globe is a perfect complement for both interior design and educational purposes. Its compact size makes it ideal for display on desks, bookcases or coffee tables, adding a touch of style to any room. The accurate details of meridians and parallels give the globe a refined and realistic appearance, enhancing the viewing experience.
In addition, the globe can be coloured as desired, allowing for creative customisation that makes it unique. Whether you use it as a decoration or an educational tool, this 3D globe will be a beautiful addition to your home or office.
By using a flashlight or small lamp, this model allows students to explore the phases of the moon, the alternation of day and night, and the changing seasons. It also illustrates the Arctic seasons, solar insolation at different latitudes, and solar and lunar eclipses. Additionally, it serves as a tool for understanding the Earth's coordinate system, including the equator, meridians, parallels, and latitude and longitude.
The model can also be used to retrace the Apollo space missions around and to the moon and retrace the orbits and the route taken in order to accomplish the missions.
This hands-on approach provides a visual and interactive way to grasp Earth's movements and their effects.
Example of moon phase demonstration with LED flashlight:
In the following image an example of studying the phenomenon of partial and annular solar eclipses with the moon model and a spherical lamp to simulate the Sun:
To insert the globe in the stand simply widen the holder gently so that the stick fits into the holder.
To join the two-part pieces, use glue suitable for plastic materials, align the pieces correctly and allow to dry.
Insert the stick into the globe, insert the globe holder into the base and insert the globe into the holder. Check that the globe rotates freely.
A 3 mm or similar rod of 124 mm in length is required as a rod for the globe.
Use a 3 mm diameter and 124 mm long stick (e.g. a wooden skewer or similar) to pass through the globe. If you do not have one, print and use the rod included in the STL files.
Be sure to mount the halves of the 3d-printed parts correctly and in alignment, otherwise rotation of the globe may be difficult.

This set is great with my Complete Solar System Model 1:1,188,500,000 scale to better understand the positions of Earth and the Moon relative to the other planets in the Solar System and the Sun, and to study astronomical phenomena in our solar system.
For more information, downloadable resources including all model data in PDF format and an editable Excel spreadsheet, 3D files of all planets, rings, a piece of Sun and major moons are available and please refer to the main model page and description of the Complete Solar System Model 1:1,188,500,000 scale at the following link: https://makerworld.com/en/models/446109-complete-solar-system-model-1-1-188-500-000-scale
