This is a clue towards the solution of the Centrifugal Puzzle Box which is a puzzle box that is solved/unlocked by spinning the box on a flat surface.
This 3D printed keyring (sold separately) contains embedded within it, using a special wax that is trapped within the keyring during the 3D printing process, a QR code and the word 'CLUE' above it (just to make it that bit more obvious), if the user is stuck while solving the Centrifugal Puzzle Box they can choose to reveal this clue by using an IOS device with a camera (iPhone, iPad, iPod Touch 4g) to read the QR code by using a barcode reader application (tested with an app called 'Scan') reveal the text "A=1 B=2 C=3" on the device's display which should help the user decode the message on the puzzles lid helping them to solve the puzzle and open the lid.
Please note that the keyring attachment (metal part) is not included.

@joabaldwin Unfortunately it's not quite that simple as when the file is uploaded, Shapeways automatically deletes all internal geometry so this effect will not occur so a 'invisible' escape hole needs to be created of size 0.01mm so this geometry does not get deleted as it is seen as one shell but the support material does not escape. For more info look at this forum post but ignore the second post as some of the info is wrong but gets corrected later on:

@Maundy Thanks! I didn't know you could do that. Do you simply have a floating object inside with reversed normals?

@joabaldwin @tjjos Hi, glad you like the puzzle! This keyring is printed in Frosted Ultra Detail which is transparent (at this thickness) but the opaque text and code are created by creating 'empty space'/voids in the centre of the keyring when designing, when it is being printed these empty spaces in the keyring get filled with a wax like support material (which is opaque) which supports the wall above the void, once printed you get this support material trapped within the solid object and looks like the pictures I uploaded. I hope this explains.

I was wondering the same thing... How did you manage to have both colors printed like that? Excellent job by the way.

@Maundy that's genius! Great puzzle, so simple and deceiving. How did you get the multiple colors on this keyring clue?
