R010-P17: Development of Assembling Frame to Support a Handmade Globe

3D Modeling
Background & Objectives
The Dagik Earth Project is an educational
and science outreach initiative that uses a
balloon and a projector to project a
“spherical Earth” in classrooms [1].
Combining both digital and analog
approaches is an effective strategy for
expanding outreach. To this end, a
handmade globe has been proposed as a
subproject.
Previously, gachapon capsules were

used simply as molds for handmade
type Dagik Earth.
globes.
We designed an original craftable frame that fits directly inside
the capsule in order to recreate the tilt of the Earth’s axis.
Frame to support a Handmade Globe
The desktop
handmade globe is
shown in Figure 2. The
frame features
magnetic poles,
allowing it to rotate
smoothly and be easily
detached.

The 3D model was created with
OpenSCAD, a script-based 3D CAD
software. Since it is script-based, it has
high compatibility with generative AI.

The G-code, which contains machine
instructions for 3D printing, is generated
using OrcaSlicer, Cura, or QIDI studio.

Mass Production
We manufacture the components using these 3D printers.

BOM Check
By placing four Daiso mini neodymium
magnets into the groove, you can attach it to
steel desks. You can be mounted wooden
desks using four wood screws.
Placing the parts on the tray triggers the
Bill Of Materials check.
The wall-mounted handmade globe is
shown in Figure 4. By placing magnets, you
can attach it to whiteboards or refrigerators.
It can also be wall-mounted using wood

Supplied inside gachapon capsules
To capture children’s interest, we packaged all components
inside gachapon capsules.
This project follows a STEAM (Science, Technology, Engineering,
Ars, and Mathematics) learning model, which bridges technology,
engineering and creative hands-on creation with scientific
discovery.
We aim to trigger interrest through technology (T) and
Engineering (E), develop it through hands-on making, and
ultimately guide learning toward the science (S) behind the globe
content.

We considered plastic injection molding, but 3D printing is
better for our volume.
Conclusion
We have developed a frame for handmade globe, are currently
conducting the Production Validation Test (PVT).
If you are interested in integrating this package into your
outreach operations, please feel free to contact us.
