We designed a hidden hinge for an outdoor packaging box service, and we particularly wanted to create this product with our own creativity - this was not only an interesting attempt, but also allowed us to fully exploit the potential of 3D printing and show the world the infinite possibilities of 3D printing technology.

Before assembling the hinges, we lubricated the bolts.

You need 7 M4 screws that are 30 mm long, 7 M4 bolts, and 4 M4 washers.
