E20_Busbar_RevA

Create a parametric CadQuery model in Precision mode. Return a single raw JSON object with the top-level keys `title`, `param_schema`, and `script`. Set `title` to `E20_Busbar_RevA`. Use TextoCAD's native parameter schema and include a complete `build(params)` function that returns one solid. Do not wrap the JSON in quotes or Markdown fences. Model a left-to-right symmetric copper busbar with two level horizontal end tabs and a raised central platform. Use millimeters throughout. Define these editable parameters: - `length` = 120, finished length along X - `width` = 12, width along Y - `thickness` = 3.5, uniform material thickness - `end_to_inner_wall` = 8, horizontal distance from each end face to the corresponding vertical wall face that faces the center of the part - `platform_underside_height` = 5, measured from the bottom faces of the end tabs to the underside of the central platform - `inside_bend_radius` = 0.5, used for all four 90-degree bends At the default dimensions, the end faces are at X = 0 and X = 120, and the inward-facing vertical wall faces are at X = 8 and X = 112. The end tabs span Z = 0 to Z = 3.5. The central platform spans Z = 5 to Z = 8.5. Build a closed X–Z side profile using straight segments and tangent quarter-circle arcs. Each bend has an outside radius equal to `inside_bend_radius + thickness`, giving 4.0 mm at the default settings. Keep the thickness constant through all bends. Extrude the profile along Y by `width`. Include no holes or slots. The default result must be a single solid with a bounding box of 120 × 12 × 8.5 mm.

Parameters

Every value above is a live dimension. Open a model like this in the editor and each one becomes a slider you can drag before exporting.
