Intercoolers are used as a cooling mechanism, for instance for a car engine, by maximising the air-flow around the engine.
Your task is to design and construct a prototype intercooler, based on a cube, to house a model engine which requires cooling.
Intercooler Specifications
two opposing faces to be punctured by a diamond shaped hole in the centre, which should be as large as possible without weakening the structure or allowing the 'engine' to fall out
the other two opposing faces to be punctured by 4 holes to take support tubes (drinking straws will be used in the prototype)
the intercooler must support the engine when suspended by the support tubes
You have available to you:
A3 sheet of card
Scrap paper
rulers, glue-sticks, pencils, scissors
4 drinking straws
1 model engine (you could model this with a cube constructed of 4x4x4 multi-link cubes for A3 card)
