Dovetail Cube Puzzle With Ring Compartment

This is a version of the "dovetail" or impossible cube puzzle with a small compartment which can be used to hold a ring or other small item. The assembled cube will be 50mm square.

It has been designed to be a interference fit with 3 different tolerances sets provided as needed. If you have an extremely well calibrated printer that produces very accurate parts then the 0.1mm tolerance files should be used however most printers will probably require the 0.2mm set of files to be used. There is also a 0.3mm tolerance set of files that may be required on less accurate printers or if you are printing at higher speeds or larger layer heights / extrusion widths that results in more imperfections (eg. corner bulges etc). You could also mix A and B parts of different tolerances get the right match if you wanted.
