I used AutoCad to design a set of adjustable shelves, drawers, and a slide out spinning lazy susan storage unit to better utilize the storage space in my Kallax Shelf unit. I then laser cut the parts out of 1/4″ or 1/8″ thick Baltic Birch. The adjustable shelves and drawers don’t have any hardware and require no tools for assembly.
For hardware on the lazy susan I used a pair of 14″ full extension bottom mount drawer glides. I also combined a 6″ long by 3/8″ diameter carriage bolt with a 6″ long by 3/8″ diameter hex head bolt by using a coupler to act as the center spindle. A few washers and bolts were used to secure the unit to the spindle. A few screws and some double stick mounting tape let me attach the drawer glides to the Kallax shelf unit.
