looks great!
did you use a box generator or something to get the living hinge to the right size on the wooden one? ive been wanting to make something JUST like that. thanks
I did not use living hinge, just make 2 rings to hold it.
The entire vertical part is a living hinge.
If you use Scad, Thingiverse has a living hinge generator you can download.
UPDATE!
Here is the code
