The ATLAS detector, the largest particle detector at the LHC, is one the most complex machines ever built. However, due to its complexity, explaining the ATLAS detector at a high-school level can be challenging. Below, we show how to use 3D printers (or straws & cardboard) to build a model of the toroidal ATLAS magnet system. We also suggest learning activities for the physics classroom.
