thingiverse

Two sets of six pieces assemble into a hollow cube, each piece planar. The pieces are specifically ten-ominos and nine-ominos. Three initial pieces are provided: one nine-omino, known as "piece_9_6.stl," and two ten-ominos, referred to as "piece_10_28.stl" and "piece_10_29.stl." To create a puzzle, print four copies of the 9-omino and two copies of one of the ten-ominos. The OpenSCAD code included contains detailed instructions for constructing various puzzles of this type.
