The prompt
Create a hollow enclosure half for a medical electronic device. Units: millimeters. OUTER SHAPE: Teardrop / pebble profile seen from the front. The top is a circular arc of 50 mm diameter. Two straight tangent lines run from the circle down to a narrow flat base about 16 mm wide, with all edges softly rounded (2 mm fillet). Total height is 60 mm and total width is 50 mm. Extrude this profile 25 mm in depth. HOLLOW: Shell the part with a uniform wall thickness of 2 mm. The back face (the face opposite the front face) is completely open so it can mate with a second half. The front face is closed with a 2 mm wall. JOINING LIP: On the open edge, add a continuous lip 1 mm wide and 1.5 mm tall, centered in the wall thickness, following the inner contour, that protrudes outward from the open face. SCREW POSTS: Inside, add 3 cylindrical posts of 5 mm outer diameter, 23 mm tall, rising from the inside of the front wall, each with a blind pilot hole of 1.6 mm diameter and 10 mm depth starting from the open end. Positions measured from the center of the top circle: two at x = -17 mm and x = +17 mm, 3 mm above the circle center; one on the vertical axis, 26 mm below the circle center. FRONT FACE CUTOUTS: 1. One circular through-hole of 20.6 mm diameter on the vertical axis, 5 mm above the circle center, for an encoder housing. 2. One rectangular through-window of 23 mm x 6 mm, centered on the vertical axis, 17 mm below the circle center, for a 0.91 inch OLED display. On the inner side, add a rectangular recess of 30 mm x 11.5 mm and 1 mm depth around this window to seat the display board. TOP CUTOUT: A round hole of 3.2 mm diameter drilled vertically through the top of the curved wall, positioned 12.5 mm from the open face, for a 3 mm LED. BOTTOM CUTOUT: In the flat base, a rounded-slot opening of 9.4 mm x 3.6 mm, centered on the open-face edge, for a USB Type-C port. All dimensions must be exact and the model must be a single manifold solid.
