car trim cap 3d model

Create a precise, 3D-printable replacement trim cap for the door sill/threshold of a 2011 Toyota RAV4 (XA30). The part should match the original plastic blanking cap in shape, size, edge curvature, and mounting method. Design it as a durable, low-profile automotive interior/exterior trim piece in black textured plastic, with a slightly rounded top surface and secure snap-fit retaining clips on the underside. Include clean, watertight geometry suitable for FDM or resin 3D printing. Use 2–3 mm wall thickness, reinforced clip bases, small fillets on all edges, and tolerances appropriate for a snug but not overly tight fit. Avoid logos and text. Provide the final model as an STL and STEP file, with the cap oriented flat for printing.
