Prompt
Create a technical 3D model of a rectangular junction box for 3D printing. The box must be built outward from specified INTERNAL cavity dimensions: Length 110mm, Width 50mm, and a Depth (Height) of 50mm. 1. Base and Curvature: The bottom surface of the box along its entire 110mm length must be a single, smooth, concave cylindrical surface. This curvature must bend inward towards the internal cavity, creating an arch-like opening. This concave surface must precisely follow a cylinder with a radius of 146.6mm. 2. Flat Ends: Critically, the two short end faces (50mm x 50mm) must be purely rectilinear and flat. Their bottom edges must be straight horizontal lines. The concave arc is only visible along the long sides; it is not present on these end faces. 3. Walls and Overall Body: The main body is formed by adding a 3mm uniform wall thickness outward from this concave bottom and the internal cavity walls. The top face must be completely open. 4. Lid Mounts: In each of the four internal corners (where the walls and the highest points of the curved floor meet), add solid vertical mounting pillars (bosses), 8mm x 8mm, rising to the top edge. Each pillar must have a blind screw hole (3mm diameter, 10mm deep) at the top for an M3 machine screw to attach a lid. 5. Mounting and Cable Holes: On the internal concave floor, near each of the 110mm ends, add two 5mm diameter holes centered along the width for mounting the box itself. On one of the 50x50mm end faces, add two circular cable entry holes (12mm diameter each).
