About this 3D model
This KRYPTEX is a longer variant of Hiob's 6-wheel cryptex. With a billion possible combinations as opposed to a million, it's a bit harder. Hence the unambiguously hard K instead of a C in the name. Hiob's design is based on CloudJ's design, which is nicely demonstrated on YouTube. My design uses Hiob's "Phantom" numerals but remains entirely compatible with his alternative rings in case you prefer runes or whatever. In fact, my design differs only in the following ways: The sleeves are lengthened and their ribs extended to support three additional wheels. The ends and sleeves are printed separately to facilitate use of different materials. Integrated into each sleeve is a rim which aesthetically separates the ends from the ring stack.
