Set contains 3 variations of link design (blanc, paved and for enameling) and two types of the clasp: box and loblster lock.
All parts modeled in 2 subversions: with fully closed loops and with opened loops. For more order and comfortable downloading I added STL parts archived in single ZIP file. (Because sometimes CGT has glitches and may lost some files).
All dimensions and parameters are shown on preview pictures. Renders shows come possible variants of chain design.
Box clasp model volume: 950mm^3 (ca. 9.5g for sterling silver)
