Use case: product-mockup
Asset type: industrial design concept board for a small 3D printable desk storage object.
Primary request: Design a faithful classic Pokemon Master Ball as a functional hollow USB flash-drive storage box, approximately 4 inches / 102 mm in ball diameter, with a separate small black desk cradle and a real user-inserted metal pin hinge at the rear.
Style: highly convincing polished CAD-style product render with believable matte 3D-printed plastic, refined practical proportions, soft studio lighting, warm light grey background. This is a design concept, not a finished-engineering claim.
Composition: Landscape board. Large hero front three-quarter view of CLOSED ball in its cradle on the left, smaller consistent OPEN view on the right showing usable hollow bottom cavity with three SMALL capped USB drives resting loosely inside. A small hinge assembly detail in lower right shows a short straight silver pin aligned with three alternating interlocking rear hinge knuckles, clearly belonging to the same rear hinge. Very little text, generous spacing. Do not show extra unrelated objects.
Appearance invariants: spherical form, royal purple upper hemisphere, clean off-white lower hemisphere, prominent black equatorial band, white circular front button inside a black ring centered on the equator. The lid has TWO symmetrical rounded magenta shoulder panels slightly raised on either side of a white capital M centered on the upper front. The magenta panels are part of the purple top only. Keep the iconic Master Ball appearance consistent in all views. In open view, the purple top pivots back on a discrete hinge at the REAR opposite the white front button. The M rotates with the lid. Hollow inside purple lid, roomy white bowl below, simple smooth cavity, no socket electronics and no arbitrary molded individual USB holes. A thin alignment lip and modest rim thickness, tiny flush magnet points at the front rim for closure. Front white button is cosmetic.
Cradle: a separate low charcoal-black round pedestal about 82 mm across and 16 mm tall, with a shallow concave seat embracing the lower pole, an understated purple accent ring around its base and three subtle soft contact pads. Closed and open views use the same cradle. Ball can be lifted out. Cradle does not cover the white front button. Ensure the open ball looks stable, with lid leaned back about 105 degrees from closed.
Use only these labels, legible clean technical typography: title "MASTER BALL // USB VAULT", below title "4-inch concept", beneath left hero "102 mm ball", beneath right open view "Hollow storage cavity", hinge detail "Insertable hinge pin", near base "Separate desk cradle". No other text or technical claims. Do not add USB cables, charging ports, LEDs, hands, tools, screws, battle-worn textures, wood, red pokeball coloring, Pokémon characters, or electronics.
