wall-mounted enclosure 3d model

Create a precise hard-surface 3D model of a wall-mounted electronic enclosure with a wedge shape (angled front 15°). Dimensions: 90mm width, 120mm height, depth from 30mm (back) to 40mm (front). Clean industrial design, matte black finish, slightly rounded edges. Front panel: centered rectangular display cutout 75x55mm with 2mm bezel. Below display, include circular speaker grille (30mm diameter) with multiple small perforations. To the right of the speaker, add a 19.5mm circular hole for RFID reader. Add an 8mm hole for DC power jack at the bottom front or underside. Structure: hollow interior with 2.5mm wall thickness, internal standoffs (4 corners) for PCB mounting, cable routing channel, and bottom cable exit slot (15mm). Back panel: flat surface with removable cover, 4 screw bosses, and two keyhole wall mounts spaced 60mm apart. Ensure manufacturable geometry, no organic shapes, sharp clean lines, realistic proportions, suitable for 3D printing.
