Medical Electronics Enclosure Half

Create a hollow enclosure half for a medical electronic device. Units: millimeters. OUTER SHAPE: Teardrop / pebble profile seen from the back. 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 front face (the mating face) is completely open. The back face is closed with a 2 mm wall. JOINING GROOVE: On the open edge, cut a continuous groove 1.2 mm wide and 1.7 mm deep, centered in the wall thickness, following the inner contour, to receive a matching lip. SCREW POSTS: Inside, add 3 cylindrical posts of 5 mm outer diameter, 23 mm tall, rising from the inside of the back wall, each with a through-hole of 2.2 mm diameter that also passes through the back wall. On the outside of the back wall, add a counterbore of 4.2 mm diameter and 1.5 mm depth at each hole. 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. 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.

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.
