About this model
Einstein said mass bends spacetime, and the rubber sheet is the classic way to picture it. This gravity well 3d model builds that demonstration as a tidy desk piece. A square, almost white sheet with a blue coordinate grid is stretched in a slim lilac frame on four steel posts above a lilac board. Towards the centre it sinks like a funnel, an embedding diagram whose depth follows one over the distance. A large yellow ball, the central mass, rests in the dip, and a small mint planet sits on a coral dashed orbit on the slope. The planet is the separate object gravity-well_orbiter with its origin on the centre axis, so one rotation about Z sends it around. There is no text. It covers 41 by 41 cm at 15 cm high, with 36,264 triangles. Black Hole shows the object itself, this model explains the curvature behind it.

Engine import notes
Unity GLB · FBX
Import the GLB with the glTFast package or use the FBX. 1 m in the file = 1 Unity unit.
Unreal Engine FBX
Use the FBX. The model is built in metres. Unreal works in centimetres and converts on import, so it arrives at real size (0.15 m = 15 cm).
Godot 4 GLB · FBX
Drag the GLB into the FileSystem dock. Godot 4 imports it directly, with materials. The FBX works too (Godot 4.3+ imports it natively).
Blender BLEND · GLB
Open the .blend directly, or import the GLB via File › Import › glTF 2.0.
