Prepared for production replicas of item designed by Paloma Picasso for Tiffany. STL parts contains also mirrored branches (left and ringht ones). Editable 3DM (saved for Rhino5 compatibility) included. No SubD's were used during modeling.
Two versions presented: 15 and 20mm (basic dimension). All additional needed data about the dimensions is shown on the preview pictures.
Back part (lock) is presented in two subversions (the difference between them is very small. One is with small guide groves and other one is without it)
Back side is flattened (similar to original Tiffany's item).
Parts volumes:
Model contains NO post. Because printing/casting/finishing of 0.8x11mm pin is pretty dumb thing. Good jeweller uses wire or prefabricated standard posts. For comfortable soldering and proper pin-post placement I've made small (0.8mm) holes.
