Wooden Boxes With One or Two Hinges

I have one of this seen in the web and wrote a onlinetool to create such boxes with two or three mouseclicks.

the first box have two hinges and can be opend to both sides
the second box has only one hinge and looks like a book ;-) this is a derivate from a box seen on thingiverse...

each box are attached as *.svg and *.pdf
