Slide-Together Models Made with Decagons

George Hart, the king of polyhedra-inspired sculpture, created models that are easy to build by sliding together simple shapes.

Steps

1. Cut out 12 pattern pieces from card stock. Use six different colors for an interesting model.
   
2. Slide pieces together at the slots. You will have to bend tabs out of the way and bend them back to make this model.
   
3. Refer to the picture to see what the end result will look like.
   

Notes

• The slots in the decagons cut the edges in the golden ratio.
  
• This model is related to the small rhombidodecahedron.
  
• It is also related to the small dodecicosidodecahedron.
  
• Images of the two polyhedra were created by Robert Webb's Great Stella software
