USDZ Ring Maker StarForge 3D Modeling Software

Ring Sized by US Chart Shown in AR

With AR Quick Look on an iPhone or iPad, a USDZ file, the zipped Universal Scene Description from Pixar, shows a ring at true size, and the USDZ Ring Maker writes one. US sizes 3 to 15 set the inside diameter from the ring size chart (11.63 mm plus 0.8128 mm per size), then Width, Style and Engraving give a plain, comfort fit or faceted band, 2 mm thick, with words 0.4 mm deep inside. StarForge 3D Modeling Software also gives a 3D Print STL File for 3D printing it flat without supports, a ring to try before buying.
