IKEA Kallax insert divider for 33 cm cubes
A cross-shaped divider that slots into a single Kallax cube and splits the 33 by 33 cm opening into four compartments for scarves, yarn, cables or toys. The opening measures about 335 mm on each side and 390 mm deep, so the divider is 333 mm wide, 380 mm deep and 3 mm thick, made of two panels that cross in a half-lap slot and hold each other square without glue. Small 2 mm nubs on the ends grip the melamine walls. Each panel prints flat; a 250 mm bed handles them in two pieces joined by a dovetail, which the model can include.
Cube dimensions drift a little between Kallax generations and the older Expedit, and the number of compartments you want depends on what goes in them. In SpeakCAD you type the measured opening and the layout, preview the divider in the browser at no cost, change to a three-row grid in the chat and download the STL.
