Hey, thats my attempt of designing an box for my kitchen door, underneath my sink. As there is a panel, thats used to hide the sink itself, i needed to create this a bit longer. This gets a bit unstable, but i might come along with a V2.
Check out the remix published by Martin421, he is using screws instead of this hinge.

Fusion 360 File, STL etc. is included, so feel free to modify.
