A snap assembly may include a cantilever snap and a retention body. The cantilever snap may include an orifice in a surface of a first component. The orifice may be defined between sidewalls. The cantilever snap may further comprise a cantilevered-slant protrusion extending between the sidewalls and out of the orifice at an angle relative to the surface. The retention body may be attached to a second component and configured to be inserted into the orifice from a side of the first component that is opposite of a side of the first component away from which the cantilevered-slant protrusion extends to secure the retention body to the cantilever snap. The retention body may include a retaining extension comprising a holding assembly. The holding assembly may comprise a plurality of teeth that are arrayed to form a series of step-like protrusions that step away from a contact face of the retention body.
