25 SIGNET RING BLANKS - 5 DESIGNS x 5 US SIZES
A ready-to-use library of flat-top signet ring blanks for engraving, monograms, crests and relief work. Five classic table shapes, each 12 x 12 mm, in five ring sizes from US7 to US11. Each size is modeled separately, so you can choose the right file without scaling.
DESIGNS - Round - Softened Square - Angular Diamond - Hexagonal - Shield
WHAT YOU GET - 25 STL files in millimeters (5 designs x 5 sizes) - 25 Rhino 7 files and 25 Rhino 8 files - Watertight STL meshes (digitally checked) - Solid models, not hollowed
RING SIZES (inner diameter) US7 17.34 mm / US8 18.16 mm / US9 18.98 mm / US10 19.80 mm / US11 20.64 mm
ESTIMATED THEORETICAL WEIGHT, US7 to US11 (solid: 925 silver / 18K gold / brass) Round: 9.4-10.6 g / 14.0-15.8 g / 7.7-8.7 g Softened Square: 10.5-11.7 g / 15.7-17.6 g / 8.6-9.6 g Angular Diamond: 7.8-8.9 g / 11.7-13.3 g / 6.4-7.3 g Hexagonal: 9.2-10.3 g / 13.7-15.5 g / 7.5-8.5 g Shield: 9.9-11.2 g / 14.9-16.7 g / 8.2-9.2 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.
DIMENSIONS (US7 REFERENCE, as shown in the dimension images) - Flat table: 12 x 12 mm for every design - Thickness: about 3.0 mm at the center of the table, 2.2 mm at the sides, 1.8 mm at the bottom of the band - Overall size: about 21.7 x 22.1 x 12.2 mm
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 rings are 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.
