starosek - Benchmark 2: 3D data capture

For this project, I used the Polycam mobile app (free version) to capture a 3D scan of a small spider ring. The scan was created using smartphone photogrammetry. I moved the phone around the object to capture the spider from multiple angles so the software could generate a complete mesh from the photos I took.

Mesh processing

After generating the scan in Polycam, I exported the model as a .glb file and imported it into Blender for cleanup. In Blender, I removed several small artifacts on some of the spider legs and checked the mesh for holes or non-manifold edges. I confirmed that the model was a closed manifold surface suitable for 3D printing.

Preparing the .STL and final results

Once the mesh was finalized, I scaled the object in Blender so that the widest dimension measured approximately 10 cm. After confirming that the mesh did not contain non-manifold geometry, I exported the model as an STL file, which is a standard format used for 3D printing. The STL contains the surface geometry of the object but does not include the original scan textures. My model represents the scanned spider ring as a watertight mesh and can be downloaded here.
