The prompt
A 3D CAD model of a mechanical trailing-arm alignment bracket used for keeping a conveyor platform level. The bracket is a rigid, flat triangular steel plate with three distinct mounting zones. The top-left corner features a precise machined circular bore hole (inner diameter matching a standard bicycle chain extended pin) to serve as the primary towing connection. The bottom-left corner features a secondary mounting flange for a miniature two-bolt flange ball bearing or cam follower guide wheel that tracks a parallel guide rail. The main right-side face of the triangular bracket features four tapped M6 bolt holes in a square pattern designed to hard-mount a flat, horizontal package carriage platform at a strict 90-degree perpendicular angle to the vertical axis of the chain. Industrial mechanical part, parametric geometry, clean edges, solid model, step file format style.
