Mask G - TC299 ECU Alignment Mask

Generate a precise 3D CAD multi-body assembly model of an ECU microcontroller alignment mask, specifically replicating the "Mask G" geometry for the Infineon AURIX TC299 chip, optimized for multi-color 3D printing. Key components and technical dimensions: 1. Main Mask Body (Color A - Black): - A flat, square block with outer dimensions of 27.0 mm width, 27.0 mm length, and 4.5 mm total height. The outer side walls must be completely vertical from top to bottom (straight 90-degree flush profile). - All 4 outer top corners must have a small radius fillet of 1.5 mm. - Bottom Side: A centered square pocket measuring exactly 25.2 mm x 25.2 mm with a depth of 2.5 mm to tightly fit over the 25.0mm x 25.0mm TC299 microcontroller. - Corner Alignment: Cut a 2.5 mm x 45-degree chamfer all the way through the bottom-left corner of the mask to create the open-corner alignment window for Pin 1. 2. Precisely Positioned Antenna Aperture & Ring (Color B - Yellow): - The mask must have a 3.2 mm diameter through-hole cutting straight down through the top ceiling. - IMPORTANT COORDINATES: Using the bottom-left corner of the internal pocket (Pin 1 corner) as the absolute origin (0,0), the exact center of this 3.2 mm through-hole must be positioned at X = 4.9 mm (distance from the left inner wall) and Y = 10.8 mm (distance from the bottom inner wall). - On the top face, model a concentric raised ring around this specific hole. The ring must have an inner diameter of 3.2 mm, an outer diameter of 5.5 mm, and a height of 0.4 mm above the main surface. 3. Letter "G" Indicator (Color B - Yellow): - Near the top-left corner of the top face, embed the letter "G" as a separate body flush with the top surface and 0.4 mm deep into the main body to indicate the mask type. 4. Website Text Engraving: - Engrave the text "://diagnosisdiesel.com" on the top face along the right edge area. 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. Design constraints: Strict adherence to the X=4.9mm and Y=10.8mm hole coordinates, sharp internal geometric pocket edges, and clean multi-body separation for dual-color slicing.
