Thing file
From Just Solve the File Format Problem
Thing file is a file format for things. Maybe you can put Dr. Seuss's Thing 1 and Thing 2 in it, along with Ben Grimm of the Fantastic Four. Actually, it is designed to contain models or groups of models for the MakerBot. It is actually a ZIP format archive with multiple STL files.
Other formats used by MakerBot hardware and software: MakerBot instruction file, STL, S3G, Wavefront OBJ, and X3G.
