This is a model of a triangular stool, which remained popular from medieval times up through the 18th century. The base model has over 6,000 faces, but three lower LoD versions are also included, down to a rather simple 863-face version. The 2048-square PNG texture file was built in GIMP using CC0 images from this site.

Note: this was modelled after a woodworking project at the St. Thomas guild blog.
