Non-Modular Hexagonal Prisms: 17

Everything on this page was designed by Tomoko Fuse. The lidded boxes are made from rectangular sheets of paper: one sheet for each lid and one for each base.
 
The lidless bowls are made from square sheets: one for the bowl and a smaller one for its liner. Each of the prism-shaped tatos is made from a single sheet.
 
These models are irregular hexagons -- often called prisms. An irregular hexagon can have 4 shorter sides of equal length with 2 longer sides of equal length, or 4 longer sides of equal length with 2 shorter sides of equal length.
