Picture of Helical Shelf System
IMG_9223 2.JPG
This furniture explores how 3D printing can unlock new possibilities in form, mechanisms and personal fabrication. The shelf system is comprised of triangular helices, cogs, belts and wooden shelves. The helices move together and cause the shelves to move up and down. This example has two different helices that are attached together. Geometrically they twist in opposite directions so when they are rotated one shelf rises and the other lowers. They have the same rotational frequency but have different heights so the shelves move to the full parameters of the height of the helices. The helices move through helical components that are screwed into the wooden shelf. The feet at the bottom are functional and sculptural, bracing the rods and housing each cog and belt. The helices and feet are great examples of the complex forms easily achievable with a cheap 3D printer.

The included parametric grasshopper file enables anyone to create their own variation of the helical shelf principle. The instructions included are for the version in the photos. This is at first prototype stage and initially I intended for a handle to cause the helices to rotate however there was too much friction so now I lift one of the shelves and this causes the kinetic change and the other shelf moves in the opposite direction. A clasp connects to a hole in the large cog and prevent the shelves from moving from a desired position.

Wonderful! Do you have a video to show off the moving shelves?
