The prompt
Generate a precise 3D CAD multi-body assembly model of an ECU microcontroller alignment mask for electronic prototyping with exact millimeter dimensions, optimized for multi-color 3D printing. The assembly must consist of distinct intersecting or embedded bodies to allow different color assignments. Key components and technical dimensions: 1. Main Mask Body (Color A): - A rectangular block with overall outer dimensions of 45.0 mm width, 35.0 mm length, and 3.5 mm total height. - Bottom Side: A centered square pocket measuring 25.2 mm x 25.2 mm with a depth of 2.0 mm. Inside this pocket, apply a 1.5 mm x 45-degree chamfer on the bottom-left corner to match Pin 1. - Top Side: A solid 1.5 mm thick top ceiling covering the pocket. Right in the geometric center of this top face, there is a through-hole cylinder with a diameter of 3.0 mm cutting down into the pocket. - Mounting Wings: The left and right margins form step-down side flanges with a thickness of 2.0 mm, each featuring a centered 3.2 mm diameter through-hole for M3 screws. 2. Pin 1 Orientation Indicator (Color B): - On the top face, directly above the internal 45-degree chamfer corner, embed a separate 3D geometric shape (an arrow or a prominent triangle pointing to the corner). It must be a separate body embedded 0.4 mm deep into the main body and flush with the top surface. 3. Korhex Antenna Ring Guide (Color C): - On the top face, model a concentric raised ring (boss) around the 3.0 mm center through-hole. The ring must have an inner diameter of 3.0 mm, an outer diameter of 6.0 mm, and a height of 0.4 mm above the top surface. This ring must be generated as a separate body for distinct color assignment. 4. Website Text Engraving: - Engrave the text "www.diagnosisdiesel.com" on the top face of one of the mounting wings or along the top edge of the main body. The text must be cleanly extruded as a negative recess with a depth of 0.4 mm, sharp edges, and a clean stencil-safe font suitable for 3D printing identification. Design constraints: Sharp geometric edges, clean 90-degree angles, completely flat surfaces, no organic curves, and clean multi-body separation for multi-material slicing.
