R010-P17: Development of Assembling Frame to Support a Handmade Globe Yukinobu KOYAMA, KINDAI University Technical College Keywords: Outreach, Handmade Globe, Capsule Toy, STEAM education 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 Fig. 1. Rear-projection 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. Figure 2. Desktop handmade globe Figure 3. Embedded magnets 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. Figure 8. OpenSCAD The G-code, which contains machine instructions for 3D printing, is generated using OrcaSlicer, Cura, or QIDI studio. Figure 9.

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 Figure 4. Wall-mounted screws. Handmade Globe. Cost & Time Estimation 3D printing parts Arc x3 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.

Conclusion We have developed a frame for handmade globe, are currently conducting the Production Validation Test (PVT).
