The prompt
Design a complete premium ultra-slim wearable wrist band called VELORA, including its original signature locking mechanism. Create an approximately 180 mm long, 20 mm wide, 2.5–3 mm thick curved wrist band. Make it ergonomic, lightweight, smooth and minimal, with rounded edges and a premium leather outer surface over a thin rigid internal structure. The band must be screenless, with no display or camera. At the two open ends, create a completely original flush mechanical locking system, NOT a normal watch buckle, pin buckle, magnetic clasp, butterfly clasp, or ordinary bracelet clasp. Use a sliding tongue-and-receiver design: one end contains a slim receiving channel and the other contains a matching reinforced sliding tongue. When inserted, a concealed spring-loaded locking element automatically engages. Use two small recessed side release surfaces that must be pressed before the tongue can slide out. Include mechanical stops to prevent accidental separation. Keep the lock as thin and compact as possible while remaining mechanically realistic. Smoothly integrate the lock into the band so it looks like part of the Velora identity rather than an added buckle. Leave internal protected space for miniature electronics and wiring. Separate the band, internal structure, outer layer, tongue, receiver, release parts and locking components into logical components. Make dimensions editable and create a detailed parametric CAD model suitable for further engineering refinement and STEP/STL export.
