IKEA Lack side tables are favorites of makers worldwide, because they're cheap, readily available and easily hackable. People are making everything from them - from server racks to 3D printer enclosures.
But the Lack has one downside - the double-pronged screws have to be rightened manually, as no standard tool will fit them. Not anymore - I created the Lack Wrench. 3D printed tool you can attach do electric drill and use it to tighten the Lack legs.
In addition to printed part, you'll need:
- M8 screw with hex head, about 20-30 mm long
- M8 nut
- M8 washer, preferrably wide one
Stick the screw trough the hole in printed part and secure with a nut. Mount the protruding part of the bolt into the drill chuck.
