The LACK Shelving System enables the classic IKEA LACK side table to form unlimited combination of shelves with 3D printed joints.
It provides a choice of shelf that is flexible, cheap and easily accessible.

APPROACH TO THE FIVE PRINCIPLES OF DEMOCRATIC DESIGN:
- The resulted shelf feels very open and allows maximum sunlight to travel through thanks to the minimalism of LACK table.
- The arrangement of shelf can be decided by individual users for their specific needs.
- Installing the joints only require drills on one side of legs. No damage is done to the table surfaces.
- It provides large surface area and volume for storage with any layout such as stright, L-shape, U-shape and stepping.
- The size of framework structure allows storage of large and extra long objects.
- The joints and extensions can be installed or replaced when the shelf is in place, without dismantling the whole shelf.
- The shelf is incredibly rigid despite that it is formed by individual components. Refer to suspension testing photo for rigidity.
- The geometry of joints help the shelf to resist lateral load and bending moment.
- The shelf can handle decent amount of weight as a result of short span between legs and thick elements.
- The system is modular and flexible. It can be extented, reformed or reused anytime in the future.
- The printed parts are optimised to consume as little material as possible while maintaining strength.
- The storage space created is very economic. The average price per volume or area is much lower than other shelves.
- A whole wall of shelf can be easily transported with small cars thanks to the compact packaging size of LACK table. Delivery cost is much lower for average customer.
- Chose any rigid filament. Consider dimensional shrinkage if use high temperature filament such as ABS or PC, etc.
- Print the joints with decent amount of infill, more than 25%.
- To quickly install a large number of tables, print the leg spinner and put it on a driver with 1/4"(6.35mm) hex square nut.
- Drill on legs only after the tables are assembled and put together in place. This method compensate for the inaccuracy and inconsistancy of leg placements.
- Drill the legs with 3mm or 4mm bits through the holes on joints.
- Install the foot/damper only on the bottom row of tables.
