About this print

A programmable cryptex puzzle that can be set to any five-letter combination, with extended versions supporting six or seven letters for those with larger print beds. The design is used as a mechanical puzzle box or novelty gift, hiding a small compartment behind a rotating letter-ring lock. PLA is a practical choice for the interlocking rings and core tube, as the material holds tight tolerances well and produces smooth sliding surfaces suitable for the locking mechanism.

Original maker's notes

There are many cryptex models around, but this one can be set to any 5 letter word you want.

*** NEW ***
If you have a larger print bed than my little 120mm one you can now print 6 or 7 letter cryptex! Just use cryptex_central_support_6 and cryptex_core_tube_6 for 6 letters and their _7 versions for 7. Dont forget to print extra letter rings.

NEW: Alternative skull end, a combination of the original ball end and thing:11953 - elvis the printable skull. Perfect for a pirate themed cryptex. NOTE: Print at 50% size to match the rest of the parts (CAD package would not shrink Elvis)

New2: Ring2 now features anti-pick features. This makes trying to guess the code by testing the resistance of the rings to turning much more difficult.

Folk who have already printed ring2 can add these features by filling 0.5mm groves into the sides.

Alternative ring1 added with reversed letters for easier printing. I found this more difficult to get a good paint finish, but I'm not too good with a brush. Print with inlay versions of locking ring and spacer ring.

Formatting may have been simplified. These are the independent maker's instructions and fitment claims; Hark Tech has not independently verified them.

Printing Programable Cryptex

For Programable Cryptex we would normally reach for PLA — it is easy to print, low-odour and plenty strong for everyday use. We set the layer height, wall count, infill and supports to suit the model and how you will use it, and those choices are already priced into your instant quote. Want a specific colour or material? Tell us and we will match it where we can.
