1. A device, comprising:
a housing including:
a first cavity,
a second cavity,
a third cavity, and
a fourth cavity;
a first laser disposed at least partially within the first cavity, the first laser being configured to output a first laser beam in a first direction;
a second laser disposed at least partially within the second cavity, the second laser being configured to output a second laser beam in a second direction that is different than the first direction;
a third laser disposed at least partially within the third cavity, the third laser being configured to output a third laser beam in a third direction that is different than the second direction;
a fourth laser disposed at least partially within the fourth cavity, the fourth laser being configured to output a fourth laser beam in a fourth direction that is different than the third direction and that is opposite the first direction;
a first cover coupled to the housing and at least partially enclosing the first cavity;
a second cover coupled to the housing and at least partially enclosing the second cavity, the third cavity, and the fourth cavity; and
a body removably coupled to the housing, at a location between the first cover and the second cover, the body including a fiducial configured to be aligned with at least one of the first laser beam, the second laser beam, the third laser beam, or the fourth laser beam.
