Number Safe - Cryptex

Version 2 available

Version 2 can be printed without supports, has tighter solerances and is smaller while keeping the same inside dimensions. It can be found here.

A larger Version with 6 digits is available here.

A number safe with an adjustable code that you can use for a creative gift box.

You can set the code by pressing the number rings onto the lock rings. Make sure the number you want is aligned with the hole.

When all four rings are in place, you can use a little glue to attach the end cap. There is no load on the end plate, it just prevents anyone from seeing the lock mechanism.

Have fun!
