Below-Knee Prosthetic Socket with Mounting Plate

Create a below-knee prosthetic socket with an integrated mounting base plate as a single solid body. The socket is a hollow lofted shell. At the top, the opening is an oval/kidney shape approximately 110mm wide and 120mm deep front-to-back, with the front edge (tibial side) sitting approximately 15mm higher than the rear edge, giving the brim a slight forward tilt. The brim has a gentle outward flare of approximately 5mm radius. The body tapers smoothly downward over a height of 160mm, narrowing toward the base. The cross-section transitions from the oval brim to a more rounded rectangular shape at the bottom, approximately 70mm wide and 60mm deep. The outer surface has a slight organic waist — narrowing slightly in the middle third before widening again toward the base, following the natural contour of a lower leg. Wall thickness is uniform at 3.5mm throughout the socket body. At the base of the socket, extrude a flat square mounting plate 80mm x 80mm x 8mm thick, centred on the base of the socket body and integrated as one continuous solid — no separate part, no gap or joint between socket and plate. The bottom face of the plate must be perfectly flat. Add 4x circular through-holes in the mounting plate, each 6.5mm diameter, positioned 15mm from each edge at the four corners of the plate (i.e. at coordinates 15,15 / 15,65 / 65,15 / 65,65 from one corner of the plate). Add a 1mm chamfer to all sharp outer edges of the mounting plate. The entire body is one single solid shell — socket + base plate merged. No separate components. Material is not specified — geometry only. Export as STEP or SOLIDWORKS part file.
