Puzzle description:
Parcel post is an old puzzle by an unknown designer. 18 cuboids are to be packed into a cuboid box. The size of the box is 6x18x28, the pieces are 2x4x9, 2x5x18, 2x5x21, 2x6x7, 2x6x10, 2x6x13, 2x7x18, 2x8x18, 2x9x11, 2x9x13, 2x10x11, 2x11x11, 2x5x9 (2 pieces), 2x7x8 (2 pieces), and 2x7x13 (2 pieces). The measures are taken from http://billcutlerpuzzles.com/docs/blockpacking.html.
If you can read German: Mehr Informationen gibt es in https://welt-der-geduldspiele.blogspot.com/search?q=3D-Druck
Printing instructions:
The puzzle is printed with a size of 5mm per length unit. The STL file was generated using PuzzleCAD: https://www.thingiverse.com/thing:3198014.
Prints are fine with no supports.
I printed the puzzle in PLA at 0.1 mm layer height.
Puzzle difficulty:
The puzzle is difficult because of the large number of pieces. Unfortunately there is no solution where all pieces lie flat in the box. Where to place the vertical pieces?
