OVAL SIGNET RING BLANK 14 x 12 MM - 5 US SIZES
A classic flat-top oval signet ring blank, ready for your own engraving, monogram, crest or relief. The oval table is 14 mm along the finger and 12 mm across in every size. Each ring size is modeled separately, so you can choose the right file without scaling the whole model.
WHAT YOU GET - 5 ring sizes: US7, US8, US9, US10, US11 - 5 STL files in millimeters, one per size - 5 Rhino 7 files and 5 Rhino 8 files - Watertight STL meshes (digitally checked) - Solid model, not hollowed
SIZE CHART (inner diameter / estimated theoretical weight, solid: 925 silver / 18K gold / brass) US7 17.34 mm 8.6 g / 12.9 g / 7.1 g US8 18.16 mm 8.9 g / 13.3 g / 7.3 g US9 18.98 mm 9.2 g / 13.7 g / 7.5 g US10 19.80 mm 9.5 g / 14.2 g / 7.8 g US11 20.64 mm 9.7 g / 14.6 g / 8.0 g Weights are calculated from the model volume using 10.36 g/cm3 for 925 silver, 15.5 g/cm3 for 18K gold and 8.5 g/cm3 for brass. Actual weights vary with alloy, casting and finishing.

PRINTING AND CASTING Made for high-resolution resin printing and investment casting. The STL meshes have passed digital geometry checks. Physical print and casting test results are not included. Supports, resin settings, shrinkage compensation and finishing allowances depend on your own workflow.
IMPORTANT INFORMATION - Digital 3D files only. No physical ring is included. - Gold images are computer-generated renders. - Choose the file for your ring size instead of scaling the model. - You may cast and sell physical jewelry made from these files. Sharing, redistributing or reselling the digital files is not permitted.
