The prompt
Design a 3D-printable box (base) in OpenSCAD for a MediFlow hospital scanner. The box holds an ESP32 DevKit v1 and takes a snap-on lid. Parameterise every size at the top of the file. Units mm. Output base.stl, plus base_parameters.txt listing every value used, plus closed_view.png and cutaway_view.png showing the lid on the box. OUTSIDE - Outside: 75 x 49, height 26, corner radius 4 - Walls 2, floor 2 - Inside cavity 71 x 45 (before the lid lip) BOARD: ESP32 DevKit v1 (from the board drawing) - Board 51.5 x 28.0, thickness 1.6, centred - Mounting holes 46.5 x 23.0 centre to centre - Standoffs: 4, outside diameter 6, 5 tall from the floor, holes 3.2 (for M2.5 screws or inserts) - Tallest part on the board: 13 above the board top (assumed; check) OPENINGS - USB opening on the LEFT short wall, 9.6 wide x 4.0 tall, centred on the board's USB port [CHECK USB-C or micro-USB] - Air outlet on the FRONT long wall: 8 slots, each 2 wide x 8 tall, in 2 rows (heights 11 and 19) x 4 columns (x = -7.5, -2.5, 2.5, 7.5) SNAP WINDOWS - 4 windows, one per side, centred. Each 9 wide, 2.4 tall, with its top edge at the box top - The lid's tabs click into these windows CHECKS BEFORE EXPORT - The board fits inside the cavity with clearance - The space above the board (up to the lid) clears the reader hanging from the lid, which sits about 22.4 from the floor - The USB opening lines up with the board's USB port - Standoff holes line up with the board holes - Walls are at least 1.5 thick everywhere
