Fully prepared and tested STL files and 3DM source of 6 basic variants of design. Totally 48 models (6 designs, 2 versions of pendant and 2 variants of stone setting)
Versions for RIGHT assembly (Head and body for soldering) and variant for LAZY people who don't like to soldering parts.
Depth for HOT enamel 0.35mm.
Basic dimensions ca. 20x20mm (as shown on preview pictures)
Gem: 2.4mm (2.5mm is also possible for setting in version with prongs).
Models volume varies from 190 to 230mm^3.
Weight for sterling silver depends on design and varies from 1.9 to 2.3g
OBJ's are untested (anyway OBJ format is useless for production), exported from Rhino as mesh and as NURBS. I added OBJ's just for better publishing and placement after stupid recomendations of CGtrader (probably for smart heads from CGt quantity of junk and thumbs is more important than quality of models).
