This tan cut and folded paper model has a ring of five points at the top, a ring of five points at the bottom, and two rings of five points toward the middle. Each of the top and bottom points is surrounded by four polygons – two adjacent irregular quadrilaterals and two adjacent relatively large triangles. Each of the middle points is surrounded by three polygons – a parallelepiped and two small triangles. Numerous polygons are coplanar. A paper tag on the model reads: DT 7. A mark in pencril reads: No. 293 (/) DT7.
