Karin Aoi from Masakazu Katsura's DNA² (D・N・A² ~何処かで失くしたあいつのアイツ~) — the time-traveling DNA Operator from a dystopian future, tasked with preventing overpopulation by targeting the "Mega-Playboy" Junta Momonari. Focused on rational structure and perfect combination of function. Pursued aesthetic appearance and optimized internal structure to ensure strength, durability and practical use — capturing her iconic futuristic purple bodysuit, chin-length light blue hair, green eyes, playful-yet-dangerous vibe, and sci-fi gadgets like her DCM gun. At 30 cm height this version offers excellent detail visibility while remaining compact enough for shelves, desks or display cases.
30 cm Karin Aoi (DNA²) Figure Version
Print Settings:
Material: PLA (recommended for good detail and easy printing)
Layer height: 0.12–0.16 mm (balances detail and print time)
Infill: 20–25% gyroid or cubic (good strength-to-weight ratio)
Supports: Minimal tree supports only where absolutely needed (panel tabs / overhangs >55°), 10–15% density
Outer shell: 3–4 perimeters (1.2–1.6 mm wall thickness) for added durability
Brim: Yes, 8–10 mm (improves bed adhesion, easy to remove)
No supports on outer main shell surfaces
Estimated print time on K1 / similar fast CoreXY printer: ~8–14 hours depending on exact speed settings
Print orientation: upright or optimized split parts to minimize supports
90 cm Karin Aoi (DNA²) Figure Version
Print Settings:
Material: PLA+ or PETG recommended (better layer adhesion and impact resistance at this size)
Layer height: 0.20–0.28 mm (faster printing, still good visual quality at viewing distance)
Infill: 15–20% gyroid / cubic / lightning (keeps weight reasonable while maintaining rigidity)
Supports: Tree supports only on critical overhangs (panel tabs / complex features >50–55°), 8–12% density
Outer shell: 4–5 perimeters (1.6–2.0 mm wall thickness) + top/bottom 5–7 layers for extra strength
Brim or raft: Yes, 10–15 mm brim (essential for large footprint and bed adhesion)
No supports on visible outer shell surfaces
Estimated print time on K1 / fast printer (or split into sections): 25–55+ hours total (strongly recommend splitting large parts in slicer or pre-split version)
Print orientation: print main body sections vertically or horizontally depending on your build volume
