The Protogami is a hexa-kaleidocycle design and engineer aid that consists of six linked tetrahedral pyramids. Each pyramid displays a particular plastic resin in four different finishes (i.e. high polish, 600 grit stone, no polish, medium bead blast).

6 popular types of plastic resin used today:



Polycarbonate (PC)

Thermoplastic elastomer (TPE)

Glass-filled nylon (PA-GF)

High-density polyethylene (HDPE)

The Protogami is just one of many tools that can help students, designers and engineers visualize the difference between different finishes on a variety of plastics for their projects.
