Wormhole Wall Art – 3D Gravity Well Optical Illusion

Futuristic 3D-printable wall art inspired by wormholes, gravity wells and the geometry of spacetime. Two rectangular grid surfaces are joined by a curved, hourglass-shaped tunnel; concentric rings and radial lines create a strong illusion of depth, like a portal through spacetime. Good for gaming rooms, offices, studios and modern interiors, and it looks best in matte black filament. It can be scaled to any size; larger sizes show the detail better. Recommended print settings (from the creator): material PLA, preferably matte black; layer height 0.20 mm; nozzle 0.4 mm; 2 wall loops; infill 15%; supports none if properly oriented; moderate print speed; print flat on the build plate if the geometry allows. The thin grid elements need a well-calibrated first layer and consistent extrusion. Actual settings depend on your printer, filament and scale.
