3D model description

Pieces of Eight is another invention of Stewart Coffin (his design #77). It consists of eight pieces, all different. These pieces can assembled into a cube and other shapes. It is similar to his Peanut Puzzle but based on cubes rather than rhombic dodecahedra. I have never owned a copy of this puzzle so I wanted to make one.

I've sized the pieces so that the final cube is 6 cm on a side. No supports are needed when printing these pieces, with the exception of piece 6 which just needs a little help (see below).

3D printing settings

Supports are not needed except for piece 6. Piece 6 needs only small supports for two horizontal sections which start about 1 mm above the build plate. I set the overhang threshold to 40 degrees so that supports are only generated in these areas (see screen shot).

Pieces 1, 5, 6 and 7 are printed horizontally, while the other 4 are printed vertically. The vertical pieces take 50% more time to print.
