This is a 3D printed molecule model of Caffeine, C8H10N4O2. The atoms are 3D printed in the correct ratios based on data from the Cambridge Crystallographic Database. It is mounted on a walnut-wood base in the shape of a coffee bean. The model is 16 cm high, 12 cm wide and 6 cm deep. More about Caffeine you can read on WikiPedia or PubChem.
