9-wheel Kryptex

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 to crack. 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.

How I Designed This

I extended parts A and B of Hiob's cryptex design by 36.6 mm to accommodate 3 more discs.

Filament Selection & Finishing Touches

I selected the following materials:

• ColorFabb™ steelFill™ filament for the decagonal endpieces of parts A and B; black PLA for the cylindrical sections
• Dark brown PLA for inner wheels
• Cherry wood PLA for outer wheels

I sanded the steel- and wood-infused parts a bit and brushed them with steel wool. This improved the appearance and lightened the color of non-recessed areas so that numerals and index marks stand out. I sanded the sides of the assembled wheels a little till they all turned easily.
