18 mm Signet ring Pack 3D print model

Jewelry signet ring models with round 18mm top for 5-Axis CNC and SLA, Micro-SLA, DLP, SCP, MJM 3D printing.

This pack offers 52 sizes of solid and hollow signet rings + BONUS 52 sizes of signet rings with room for enamel or monogram.
All ring sizes are 0.25 mm pitch. This corresponds to the German sizes. But rings are divided into four files, for example:

first .3DM file 12 mm - 24 mm (13 ring sizes)
second .3DM file 12.25 mm - 24.25 mm (13 ring sizes)
third .3DM file 12.50 mm - 24.50 mm (13 ring sizes)
fourth .3DM file 12.75 mm - 24.75 mm (13 ring sizes)

13 x 4 = 52 ring sizes

.STEP files are divided according to the same principle.

A total of 12 .3DM files (solid + hollow + bonus enamel models)

Next

Number of solid .STL files - 52
Number of hollow .STL files - 52

Number of solid .OBJ files - 52
Number of hollow .OBJ files - 52

All .STL files are centered on the Y axis, then turned upside down and placed on the floor for easy 3D printing.
All .OBJ files are centered on all axes.
The mesh of .OBJ files, is the same as in .STL files. So you can use it for printing or save it to .STL format if you need .STL in default position.

Also, the package contains .ZTL (ZBrush 2021.1) and .BLEND (Blender 3.2) files, in which all ring sizes are centered and collected in one file.
For example:

one .BLEND file with all solid ring sizes
and one .BLEND file with all hollow ring sizes

Likewise:
one .ZTL file with all solid ring sizes
and one .ZTL file with all hollow ring sizes

Useful tip.
If you are working with Blender or Zbrush and are running out of Hard Drive space, you may need to remove the autosave / quicksave files.
You can do this here
for Blender: C:\Users\Your_User_Name\AppData\Local\Temp\Any_Autosave_File.blend
for Zbrush: C:\Users\Public\Documents\ZBrushData2021\QuickSave\Any_QS_0000.zpr

All .3DM files have been checked for open seams and fixed.
The .STL and .OBJ meshes are also checked, fixed and ready for prototyping.

By stretching these models along the Y-axis, you can turn this into an Oxford type.

The jewellery signet rings will well look in Rose Gold, White Gold or Platinum, and Yellow 18K Gold.

Blank classic rings are popular on Etsy, and you can have them engraved for more personalization or making seals.
