OBJ is a text-based mesh format from the DCC world (Blender, Maya, ZBrush). It can reference materials through a separate .mtl file; this tool reads the geometry.
The converter writes GLB, so the result loads directly in web viewers, e-commerce embeds, and most game engines.
GrandpaCAD turns a text prompt into a ready-to-print 3D model. Functional parts, organic shapes, multi-color prints. No CAD skills needed.
