Voronoi-tesselated Tetrahedron

thingiverse

Create a hollow tetrahedron using Voronoi diagrams in Meshlab for an easy print without support. Midway through the process, insert bells into the cavity to make a miniature mathematically-inspired rattle. For guidance, refer to this procedure: 1. Launch Meshlab and ensure Selected Face Rendering is on. 2. Import your watertight mesh or start with a primitive (e.g., tetrahedron). 3. Align the object to the XY plane by selecting three points and using Filters > Normals... > Transform: Rotate. 4. Add triangles as needed (100-300k is ideal) using Filters > Remeshing > Subdivision: Midpoint or Butterfly. 5. Perform Poisson-disk sampling with 50-60 samples and Voroni Vertex Coloring with BackDistance checked. 6. Remove colors to prepare for the next step. 7. Select faces by vertex quality, invert selection if needed, and delete selected faces. 8. Smooth lines using Laplacian Smooth (3-5 iterations). 9. Export mesh as .stl after resampling and decimation adjustments. 10. Scale the primitive to the desired size using Filters > Normals... > Transform: Scale before saving.
