The XYZ Diamonds is another planar origami model, made from 3 intersecting diamonds. The design is by Francis Ow, the well known folder/creator of origami hearts.
Though it looks like there are only 3 planes, joined in the middle as though by magic(!), the planar model is actually made of 6 modules. Accuracy is required in folding the modules, else fitting each unit into the next is almost impossible. The first 4 modules can be fitted in easily. The last 2 are not that easy and this is where accuracy of folds makes a difference.
The model works best with 3 colours and 2 modules of each colour.
