Parametric Open-Top Drawer

Create a parametric open-top drawer part, solid body, all dimensions in millimeters. Floor: a solid rectangular plate 193 mm x 193 mm, 3.0 mm thick, centered at the origin, bottom face at Z=0. Walls: 4 perimeter side walls rising from the floor edges, wall thickness 3.5 mm, wall height [WALL_HEIGHT] mm. No top cover — the drawer is open on top. Walls align to the outer edge of the floor, so the outer footprint is 193 mm x 193 mm. Corner reinforcement posts: 4 square posts, 10 mm x 10 mm cross-section, one at each of the 4 interior corners, running the full wall height, attached to both the floor and the walls. Each post has a vertical through-hole, 4.2 mm diameter, centered in the post, passing through the full height of the post and through the floor, for an M4 stacking screw. Cable routing cutout: one rectangular through-hole in the floor, 50 mm x 35 mm, with 3 mm corner fillets, positioned near one corner of the floor but clear of the nearest corner post. Export as an editable parametric STEP model. Create a parametric open-top drawer, solid body, in millimeters. Floor: 193 mm x 193 mm x 3 mm thick, centered at origin, bottom at Z=0. Walls: 4 perimeter walls, 3.5 mm thick, 65 mm tall, open top. 4 corner posts, 10x10 mm cross-section, each with a 4.2 mm diameter through-hole for M4 screws. One rectangular cable cutout in the floor, 50 mm x 35 mm, 3 mm corner fillets, near one corner. Drive mounting holes on the floor top face: - 2 mounting patterns for 3.5" hard drives, each pattern with 4 holes forming a 76.2 mm x 101.6 mm rectangle, 3.2 mm hole diameter. - 4 mounting patterns for 2.5" SSDs, each pattern with 4 holes forming a 61.72 mm x 76.2 mm rectangle, 3.2 mm hole diameter. Arrange all 6 patterns spread across the floor area without overlapping each other, avoiding the corner posts and the cable cutout. 4 small rectangular through-cutouts, 25 mm x 15 mm each, near 4 of the drive positions, for plugging in USB-to-SATA adapters directly. Fan port on one side wall: a circular through-hole 76 mm diameter, centered on the wall, surrounded by 4 mounting holes 4.2 mm diameter arranged in a square pattern 71.5 mm x 71.5 mm centered on the same point, for an 80 mm case fan. Inside the 76 mm circular opening, add a honeycomb hex-pattern grille for airflow protection. Export as an editable parametric STEP model.
