contour bottle 3d model

Untextured high-poly 3D model of the iconic Coca-Cola Contour glass bottle shape, re-imagined as a functional variable-volume container. The bottle is segmented. The central part of the 'mid-drift' contour is a distinct, functional external helical screw thread ring made of brushed metal. This thread facilitates the twisting and telescoping collapse of the upper glass-like body into the lower glass-like base body. The model maintains the standard 'Contour' profile in both fully extended and fully collapsed states. Cap is a standard screw-off. Geometry is clean and manifold, showing nested cylinder logic through the contour walls. Include defined grooves for dynamic O-ring seals within the nesting mechanism. Clear grey engineering render.
