Kepler is Felix Ure's third design and his first packing puzzle challenge. His description:
"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."
Machined from solid aluminum and brass, Kepler measures 55mm x 31mm x 33mm, and weighs 155g (.34 lbs) in its solved state. The brass is left unfinished, leaving it to slowly patinate and darken with use. Felix rates the difficulty as 6/10.
