Kepler Packing Puzzle

DESIGNER: Felix Ure MATERIAL: Solid Aluminum and Brass SIZE: 2.16" x 1.22" x 1.3" (55mm x 31mm x 33mm) Kepler is Felix Ure's third design and his first packing puzzle. Typical of Felix's work, the solution is elegant and surprising. Felix describes Kepler as: "The aim is to put all 11 balls inside the enclosure, then insert the lid. A pocket-sized packing puzzle that seems very simple, until it isn't." The puzzle is not solved until all eleven balls are in the container with the lid flush against the opening. Precision machined from solid aluminum and brass, Kepler weighs 155g (.34 lbs) and measures 55mm x 31mm x 33mm, in the solved state. The brass is left unfinished, leaving it to slowly patinate and darken with use. Felix rates the difficulty as 6/10. Handling Metal PuzzlesAll metals tarnish over time. Residual oil and salt from handling speed up the process and may leave undesirable fingerprints. Occasional use of our Metal Puzzle Polishing Kit with a coat of Rena
