What STL and GLTF files are
STL
STL is the standard file format for 3D printing. It describes a model's surface as a mesh of triangles without colour, texture or units, which keeps it simple and universally supported by slicers and CAD software.
GLTF
glTF (GL Transmission Format) is an open 3D format from the Khronos Group, often called the JPEG of 3D. A .gltf file describes the scene in JSON and can point to separate binary and texture files, and it loads quickly in web viewers and game engines with support for realistic PBR materials and animation.
