Shelving

Knuckle Bones is a fully modular shelving system built around a central cast knuckle. Using three main components—the knuckle, laser-cut tubing, and a press-fit bushing—the system can be configured in an endless number of sizes and layouts.

Knuckle Bones priorities structural precision, seamless assembly, and visual cohesion, with shelves supported without f ixings and knuckles retaining all six spokes to maintain a consistent, playful geometry.

The central knuckle is produced using a lost-wax casting process. A soluble core is first created to form the cavities for the inserts, over which a second layer of wax is injected.

Once the wax pattern is complete, it is coated in a plaster slurry in preparation for casting.

The Laser-cut tubing receives a machined bushing that is press-fitted into place. A specially designed slot in the tubing allows the shelves to sit securely without any fixings.

The flat, machined surface of the bushing fits neatly into the knuckle and is secured with a countersunk bolt, creating a stable, seamless connection.
