Original STL : I was not satisfied with the design. If you your printer is not perfectly adjusted it will fail. And even when it prints succesfully, hinges will brake as soon as you use it

So... I completly rebuilt it from scratch.
Now, Hinges are strong and tolerances are ok for a FDM printer.
I also included chanfers to remove it easily from the bed and have a softer feeling in the hand

Please tell me if it work for you :)

Inside : W 31(+)mm x L 67(+)mm x h6mm
(+) = you have a little extra space to grab what is inside the box
Outside : W 39mm x L 72mm x h16mm
