thingiverse

This is a tutorial on how to create a 3D printed replica of an ancient Sumerian seal using free software and tools. Here's a breakdown of the steps: **Step 1: Research and Tracing** * Search for line drawings of the Sumerian seal online * Use Google Image Search and search tool options to find suitable images * Trace the image using Illustrator and the pen tool **Step 2: 3D Modeling** * Import the traced image into Sketchup and close all faces * Extrude the faces to create a 3D model * Keep in mind the overhang/support material and 3D printer capabilities * Only extrude the parts that need to be pressed into clay **Step 3: Refining the Model** * Import the model into Blender and roll it to refine the shape * Export the model as OBJ/STL **Step 4: Adding a Core** * Import the model back into Sketchup and add a cylinder core * Keep in mind the overhang/support material **Step 5: Making it Solid** * Import the model into Meshmixer and make it solid using the "Make Solid" tool * Use MakePrintable as an alternative option **Step 6: Printing and Transferring to Clay** * Print the model using a 3D printer * Press the printed cylinder seal into clay * Allow the clay to dry for 24 hours **Step 7: Painting (Optional)** * Paint the seal using Citadel Shade: Nuln Oil The tutorial also includes a custom section on creating an ancient "3D printer" project, which involves: * Learning about ancient communication methods and technology * Creating a Sumerian seal design using free software and tools * Bending flat 3D models to create the seal shape * Transferring the design into clay using a 3D printed cylinder The tutorial is suitable for ages 5+ and requires some experience with 2D/3D software, 3D printing, and preparation. The necessary software includes Illustrator (GIMP), Sketchup, Meshmixer, and Blender, all of which are free.
