TPU/PP: little box with living hinge (flex)

Note: this thing is for flexible filament only: Either TPU/TPE or PP!

I've been thinking about how to put 'living hinges' elegantly into a print for some time now. Finally, it sparked in the brain and I made it pretty fast in Fusion360: no need for support at all, elegant full closing box - first print turned out great! voila.
 

It's very usefull: It closes save and right now I use it as safety pill box.
