See other sections of this tutorial for instructions on folding other unit variants.

Reversed Edge Connector makes it possible to join two Vertex Units, with their pyramids directed towards the center of the model.

1. Start with a square piece of paper. Crease both diagonals.

2. Fold three corners to the square’s center.

3. Fold in half on both sides along the axis of symmetry.

4. Crease by folding the left edge to the closest corner of the small square. Also, crease the line going through that corner.

5. Crease diagonals of the two small square areas. The creases should be mountain folds in the left square and valley folds in the right one.

6. Fold along the boundary of the two small squares.

7. Tuck the flap into the pocket. The unit looks like a square at this point.

8. Form the waterbomb base from the small square. The square has one solid edge and three edges with pockets. The solid edge and one edge with pocket should be the straight edges in the waterbomb base while two sides with pockets should be used for the parts of the base which are creased inside.

9. Vertex units can be connected by inserting their corners into the two pockets in the connector unit.
