Marley Dropper Outlet 65mm Alignment Tool

I need you to create an editable 3D CAD model and a printable STL of a Marley Dropper Outlet 65mm, model MC11.65, for use as an alignment tool. I have measured the physical part. Please use the dimensions below to create an approximate model. Do not invent missing details without clearly stating your assumptions. **Required files:** 1. An editable parametric CAD file, preferably FreeCAD (.FCStd). 2. A STEP file (.step or .stp). 3. An STL file suitable for 3D printing. **Measurements (all in millimetres):** - Mounting flange: square, 75 × 75 mm. - Flange thickness: 1.8 mm. - Overall depth: approximately 45.18 mm, measured from the flange face to the end of the outlet. - Wall thickness: 1.8 mm. - Outlet outside dimension, rounded side to rounded side: 67.43 mm. - Outlet outside dimension, flat side to flat side: 54.4 mm. - Outlet inside dimension, rounded side to rounded side: approximately 64.5 mm. - Outlet inside dimension, flat side to flat side: approximately 51 mm. - Outside length of the flat section: 40 mm. - Inside length of the flat section: 38.8 mm. - Two mounting holes, approximately 3 mm diameter. - Mounting hole centres: approximately 64 mm apart. - Hole centres are approximately 5.5 mm from the nearest flange edge. **Important shape information:** The outlet is not a simple circular pipe. It has a rounded profile with flat sections. Reproduce this shape as accurately as possible using the measurements and the reference photos I will provide. The flange and outlet should form one connected model. The outlet must be hollow, with an opening through it. Please: - Keep all dimensions editable as named parameters. - Make the outlet profile and flange orientation easy to adjust. - Check that the wall thickness is approximately 1.8 mm and that the mounting holes are positioned correctly. - Show me a preview before finalising the files. - Tell me which dimensions or shape details you had to estimate. - Export the final model as STEP and STL. This is primarily an alignment tool for a physical fitting that will be sealed with silicone. It is not intended to be a certified or guaranteed watertight plumbing replacement. I can supply photos of the actual part from the top, side and underside. Use those photos to refine the shape rather than assuming it is a standard rounded rectangle.

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.
