Ancient cylinder seals collection

thingiverse

Cylinder seals, actual size. Meshes based on point clouds from http://repository.edition-topoi.org. Can be used with clay, modeling clay, plasticine, play dough, etc. For each seal in this collection, I include a mesh of the original seal and meshes of two seals with increased relief that are less realistic but may look better when pressed into materials. A mesh of a simulated unrolling of the seal is also included. The scripts used to generate these from point clouds can be found in the seals and scripts folders at https://github.com/arpruss/miscellaneous-scad. Note that my modded version of nxedit, located at https://github.com/arpruss/nexus, was used to extract text point data from Nexus files (nxedit filename.nxs -x). The tools used include MeshLab for point cloud to STL conversion with automation scripts, python scripts working on point clouds and meshes (unrolling point clouds and generating solid slabs from one-sided open meshes), and OpenSCAD for automated labeling and rendering. No supports are required, but some STL files may need repairs before printing. **Copyright note:** The original point clouds were licensed CC-BY-NC-SA-3.0/DE, but the original seal has been in the public domain for millennia. I believe a 3D scan does not add copyright. However, European law may be different, so I have put the CC-BY-NC-SA notice on this file to avoid trouble.
