These are the 3D printable STL files and PuzzleCAD files for 4 3D packing puzzles I designed. They are part of a series of apparent solid packing puzzles, I have named the ARCparent Series. The goal is to arrange the pieces so that the boxes appear to be filled with an 'Apparent Solid'. The main photo shows examples. I generally sell these individually for $5 per design, but this set offers 4 for the price of 2.

Rotations are allowed for all of these puzzles. Do not be discouraged if these puzzles take longer than an hour to solve... It just means you got more puzzling bang for your buck!


ANGLE CUBE requires 13 moves total to solve. I would rate this as a medium difficulty puzzle.

CORNER CUBE requires 17 moves total. This is a fairly difficult puzzle.

DIAGONAL CUBE requires 21 total moves to solve. This is a difficult puzzle.

EDGE CUBE requires 16 total moves. I would rate this as the easiest of the puzzles, though some may disagree...


There are several sets of the files with various inset amounts to account for variability between different printers.

The PuzzleCAD file used to generate each STL is also included, along with a link to where to download PuzzleCAD in the READ_ME file. Using PuzzleCAD allows for these STL files to be generated and then printed without requiring any supports. PuzzleCAD uses a clever joint to connect the parts together to form a solid piece.

If you have any troubles with the files please contact me.
