Ring box, reverse engineered from the "degreesoffreedomco" product.

Requires six M3 screws, approximately 8-10 mm in length. Screw directly into the plastic, but not too tight to allow for rotation. You can try scaling by 133% (or any scale, really) and use M4 screws (will need to be slightly longer) if you'd like a bigger box.

Box is approximately 39 mm in each dimension at 100% scale.

Print three of each piece (total of six).

UPDATE 12/11/19: 166% scale ring box is now uploaded, it is essentially the same as the original, just scaled up to 166%, but the holes are still sized for M3 screws. Much easier to handle and manipulate than the original, which feels tiny, however this version may be too large to fit in your pocket as an actual "ring box."
