The prompt
SBR20 Linear Rail – 2000 mm Generate a single editable 3D CAD part and export it as a STEP file. Part: VEVOR-style SBR20 fully supported linear guide rail. Units: millimetres. Geometry: Overall length: 2000 mm. Hardened steel round shaft diameter: 20 mm. Shaft continuously supported along its full length by an aluminium support extrusion. Model a realistic standard SBR20 supported linear rail profile. Aluminium support must have a flat mounting surface underneath. Include regularly spaced mounting holes along the support extrusion. Rail ends square cut. The rail must be compatible with an SBR20UU open linear bearing block. Create this as a clean mechanical solid suitable for assembly in Fusion 360. Do not model unnecessary cosmetic details. Do not create a mesh. Output: One STEP file. Separate solid bodies for steel shaft and aluminium support are acceptable. Place the origin at the centre of the rail length, centred on the shaft axis.
