I made this model in order to explain the intuition behind the voronoi technique. Voronoi is essentially wireframe on the dual version of the mesh.

A mesh/graph is simply points that are linked together, its dual variant is where the faces made in the graph become points/nodes and a line/edge is drawn between the points where these faces touched.

Printing Information:

• No supports are needed as it prints flat

• Use a brim to improve adherence with the printbed

• I recommend printing both pieces in different colors so that when you hold them in front of each other, you can more easily see their inherent relation.
