Like all Guatemalans we woke up to the terrible news of the people affected by the tragedy of the Fuego volcano. We noticed a big problem was the lack of cribs for very small children who sadly were left homeless or who had to be evacuated. We decided to develop a design of that first space that a human being occupies, that could be quickly fabricated with one 6x8’ MDF panel, easy to assemble by precission fitting with no screws or adhesives, and easily transportable. More than sixty of our CEmTEC cribs (Temporary Emergency Cribs of Short Assembly in Spanish) have been built and delivered by different carpentries, sawmills and the general public using the digital fabrication that we made available Open Source with a non-commercial Creative Commons license.
