Apoferritin Protein Structure Model

This is a model of the protein ferritin from *Pyrococcus furiosus* at a scale of 1 to 1,000,000 and at roughly 6 Angstrom resolution. One millimeter in the printed model is therefore roughly the size of a hydrogen atom.

Ferritin exhibits octahedral symmetry. It consists of 24 asymmetric units. The model has to be printed 24 times. Two units are glued together to form a dimer, and 12 of these dimers can be assembled using the sticks and holes in the model.

Assembly can be tricky, have fun playing with it! (Tip: Assemble three dimers around the 3-fold axis first. Do this four times and then assemble everything)
