This is a remix of the Dice Code Box by MAKR. Changes I've made:

Adapted the outer ring to include the rune markings. The runes are recessed by .4mm and print well at .12. Originally I was planning to have the runes go right through, but this limited the options and would have needed supports to print.

I split the inner tube into two parts that press together tightly to the same overall length. This just avoids the bridge on the inner tube, but isn't required

I modified the outer tube to add an extra lug at the rear, which holds all of the rings when the correct code is rotated 180 degrees or when the inner tube is removed.

And, I changed the inner ring to have a smalled marker for the face that holds the correct code - I didn't need this part in the end, as my outer rings did not have holes right through, but I've included it here as I may remix this again with different codes and it may be useful for others.

Printed in black PLA, most part .2 other than the outer rings. Paint is a base coat of DecoArt Obsidian Metallic, with drybrush DecoArt Sterling Silver over the top
