storage box 3d model

Minimalist rectangular storage box with a sliding lid. Two separate parts: the main box and a sliding lid. The box has internal side rails (grooves) that guide the lid. The lid slides in from one short side and includes a built-in end stop so it cannot slide out completely. Smooth friction-fit sliding mechanism, no snap-fit, no hinges, no magnets. Clean industrial design, rounded edges, matte plastic appearance. Designed for FDM 3D printing with 0.3 mm tolerance. Internal space sized to hold flat sachets. No text, no logos, no symbols, no engravings anywhere on the model.
