Stepped Bushing Spacer

Create a single-axisymmetric cylindrical mechanical spacer/bushing with the following exact dimensions, all in millimeters: * Overall length: 19.5 mm * Through-hole: Ø8.00 mm, straight and continuous through the entire part * Lower/main section: outer diameter Ø15.95 mm, length 14.5 mm * Upper flange/section: outer diameter Ø27.00 mm, length 5.0 mm * The Ø27.00 mm section must be concentric with the Ø15.95 mm section and located at one end of the part. * The transition between Ø15.95 mm and Ø27.00 mm must be a sharp 90-degree shoulder, with no chamfer or fillet unless required by the CAD kernel. * The Ø8.00 mm through-hole must remain Ø8.00 mm along the complete 19.5 mm length. * All dimensions are nominal and must be modeled accurately. * The part must be perfectly rotationally symmetric around the central axis. * Do not add threads, chamfers, fillets, grooves, tapers, or other features. Generate the model as a parametric CAD solid and provide an exportable STEP file.

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.
