This wooden model is a faithful three-dimensional representation of the Exacedron Abscisus Vacuus, one of the geometric shapes illustrated in Luca Pacioli’s De Divina Proportione, with drawings by Leonardo da Vinci. The shape derives from a regular cube with its edges ‘cut away’, revealing only the outer frame: an open hexahedron, rigorous in structure yet surprisingly light in appearance.
The DAHIMO model consists of 24 triangle segments, 24 square segments, and 48 angular joints, all made of laser-cut birch plywood. PVA glue (such as Vinavil) is required for assembling the polygonal faces, while the joints fit together without glue. The assembly process requires some patience but is accessible even to those new to geometric models: just follow the correct order and the structure will come together with elegance.
Once completed, the Exacedron becomes a lightweight and refined geometric sculpture, ideal for display in a study, school, or any space dedicated to math, science, or design. This model is part of the K Series – Polyhedra from the De Divina Proportione, a collection designed to physically reconstruct the extraordinary forms illustrated by Leonardo, with a modern graphic design and compact packaging.
