I aimed for the box to be as customizable as I can. The usual parameters are there: LENGTH, WIDTH, HEIGHT, WALL THICKNESS. In addition, the corner fillet can be set, as well as the tolerance (mine is at 0.1), and the two gaps associated with the hinge (see attached picture). Ignore the “latch” parameter. I'm still trying to figure out a good latch/snap for the box.
The hinge parameters are related to wall thickness. The hinge diameter is basically twice the wall thickness, and the ball joint diameter is the same as the wall thickness. The gap between the center hinge and the outer hinges are set to ¼ of the wall thickness. All of these can be changed.
The box works for me so far. The model does get wonky if you set the wall thickness more than a quarter of the width or length. I tend to use 3 or 4mm for my walls.
