![]() Step 2: Create a new sketch on that plane. Step 1: Create a work plane that is offset from the outer surface of the ring in the XZ plane (I spaced mine off two inches, so I could still see the ring without interference.) Because we need to make multiple rings, we are going to use parameters to allow us to quickly change the text on the ring. We are now going to add the text onto the surface of the ring. I used a Stratasys uPrint printer, which prints in ABS and a support material. Since the rings are printed on to the outer chamber with about a hundredth of an inch gap, and are inaccessible to clean out any non-soluble support material, you WILL need a printer that can print in a soluble support. Second: This print requires use of a printer with a soluble support material. Plus, there is writing on the side which you do not need or probably want. This Cryptex is a fixed combination, and thus, if I give you the STL, it will be exactly as shown in the images above. I don't believe you actually want the STL file. POST-INTRO NOTE ( PLEASE READ BEFORE COMMENTING): I have recently received many comments about getting the STL for printing. IF YOU ARE CURRENTLY SEARCHING FOR, OR PLANNING ON SEARCHING FOR, THE GEOCACHE CRYPTECH (GC3K7QE) YOU SHOULD BE FOREWARNED THAT THERE ARE SPOILERS INCLUDED IN THIS INSTRUCTABLE. If you are interested in making an exact copy of my Cryptex, please skip to Step 17 , which details modifying my files to edit the combination. This should include creating parts, assemblies, extruding, cut extruding, revolving, embossing, and basic parametric modeling skills. Basic experience with your CAD software of choice is recommended. It will use Autodesk Inventor 2012, and will detail the critical steps needed to create it. This Instructable is going to guide you through the critical steps to create a CAD file for 3D Printing a Cryptex. The pictured Cryptex is currently being used as a Geocache ( ) in Minnesota ( ).

To open the Parametric Cryptex in the online OpenJSCAD preview click here stl files can be generated with the same tool. The parametric cryptex is written in JavaScript for OpenJSCAD, the. The number of code and lock rings depends on the settings. The parametric cryptex is made of 4 parts: base, lid, code ring and lock ring. This was the main motivation behind the customizable cryptex, parts designed for one 3D printer might not be functional when printed on another one, the cryptex having lots of moving parts is especially affected by this issue. ![]() It also allows to set the margins between movings parts, compensating for the printing inaccuracies of 3D printing, allowing to obtain a functional cryptex on any 3D printer. stl files can be generated to print the parts on a 3D printer. Size, number of code rings and inscriptions on the code rings can be modified and. The parametric cryptex is a parametric combination safe.
