fidget cube with flexible hinges

Js_Way has designed an flexible fidget cube http://www.thingiverse.com/thing:2093071
I love that toy. Inspired by this, I thought it would be nice to print the cubes with what ever material you like, and only print the hinges with flex, because I only have one type of expensive flex, but a lot of PLA in multiple colors.
I guess, there are other cases too, where the traditional hinges could be changed to flex material.

I have added two files called integrated_support. The hole at the top is closed on both ends (only 1 mm) for easier printing, Open the hole with a small knife after printing.
Would like to see a make.

UPDATE 3
The integrated support is now a little bit insi
