Prepared to production STL parts and source 3DM file with models of band rings with the hex ISO 7380-1 aka Button Head screws heads.
It's hommage to widely known Cartier's LØVE design. I can say: Why the obsolete slotted head was used when the modern technical generation uses mostly hex or allen keys and screwdrivers? And I'm saying it!
Collection contains THREE versions of the same design:
Lightweight (with 1.3mm thin band) Heavyweight (with 2mm thick band) Medium weight hollowed (that's just slightly heavier than lighweight version but has just a bit thinner band than a heavyweight version)
