This NFC card holder draws its creative inspiration from the iconic emblem of Celestial Being, the organization featured in “Mobile Suit Gundam 00.” With its exquisitely crafted and striking design, the emblem is instantly recognizable, making it the central visual element for the model’s conceptualization. The card holder is compatible with public transit NFC cards and access‑control key cards, accommodating cards up to 56×30×6 mm in size. It includes a built-in lanyard hole, allowing you to attach it to a backpack or keys for convenient portability. Its slim profile ensures it remains lightweight and unobtrusive, effectively preventing loss.

The model is optimized for AMS multi‑color integrated printing using PLA filament. Color schemes include white, light blue, golden yellow, and dark blue, enabling intricate multi‑color relief designs to be printed in one go without the need for gluing or assembly. The overall design features precise tolerances, allowing components to snap together seamlessly while ensuring smooth yet secure disassembly. Card insertion and removal are comfortably snug—neither too loose and prone to slipping nor too tight and difficult to extract.

The support structure has been meticulously fine‑tuned, with supports placed only where necessary to prevent overhangs. These supports are easy to remove, leaving minimal burrs after printing and significantly reducing post‑processing sanding. Relief details have been reinforced and refined to avoid breakage or stringing during printing, making the design suitable for standard FDM 3D printers. Matte‑finished PLA delivers an exceptional tactile quality, blending nostalgic anime aesthetics with everyday practicality—perfect for enthusiasts who wish to craft their own collectibles or use them in daily life.
