It’s the design we used for our toolboxes, a two part case (the outside portion is printed in two steps though to embed the logo) that holds the PCB using M3 screws, bolts through from the front, through the mounting surface, and through the inner box.
@PulsarForce has the inner box modelled and the coil-holder too, so can probably make a custom box-with-lid to be more similar if you wanted it closer to the xACv1.
