Duodecedron Abscisus Vacuus

This wooden model is part of DAHIMO’s series “Il Sogno di Leonardo”, dedicated to the physical reconstruction of some of the most fascinating geometric solids of the Renaissance. It is made of 4 mm birch plywood, laser-cut with care. The flat figures (pentagons and triangles) must be assembled using PVA glue (not included), while the angled joints fit together by pressure. For increased longterm stability, glue is also recommended for the connectors.

The kit includes 60 pentagon segments, 60 triangle segments and 120 connectors, for a total of 240 pieces to be assembled with patience and precision. As the model takes shape, it gradually reveals the internal logic of complex geometry. The finished object is light, elegant, and beautifully symmetrical. It requires attention, but rewards with a great sense of accomplishment.

This polyhedron belongs to the family of modified Archimedean solids and is characterized by its hollow, rhythmic structure that highlights transparency and movement. It was drawn by Leonardo da Vinci to illustrate the mathematical treatise De Divina Proportione, written by his friend and collaborator Luca Pacioli. Leonardo’s talent as an artist gave these geometric forms a unique spatial life through light and perspective.

Once completed, the Duodecedron Abscisus Vacuus becomes a mathematical sculpture with a striking visual impact. It fits perfectly on a table, bookshelf, display case or can be suspended, where its open lines interact beautifully with light. It is one of the most admired models in museum bookshops, appreciated by those who enjoy building with their hands and contemplating with their eyes.
