It is using m3 bolts for hinge. The latches will need some cutting down after printing, to help it release easier. It latches very tightly. I used a .4 nozzle with .2 layers. 

update: this model isn't great, with the latch being a major hassle. Sorry, I intend to fix it as soon as I learn how. 

I made this using a scad model from here:

I have included the stl and the scad file. You can alter the scad file to adjust things.
