Claim 16:
17. A vehicle interior, comprising:
a vehicle base; and
a display mounted on the vehicle base, the display comprising a display module disposed over a bottom surface of the substrate, the substrate comprising:
a 3D printed surface feature disposed on and extending from a top surface, the 3D printed surface feature attached to the top surface at a contact interface between the 3D printed and only a portion of the top surface, the 3D printed surface feature comprising:
a glass or glass-ceramic,
a compressive stress region at an exterior perimeter surface of the 3D printed surface feature, and
a central tension region interior of the compressive stress region,

wherein the contact interface has a minimum contact dimension,
the compressive stress region has a maximum depth measured inward from the exterior perimeter surface at a direction orthogonal to the exterior perimeter surface, and
the minimum contact dimension is at least three times greater than the maximum depth of the compressive stress region.
