The prompt
Modify the design so the electronics housing is made of two separate printable parts: a bottom tray and a removable screw-on lid. The bottom tray should be hollow and open at the top. The internal cavity should be 72 mm long, 52 mm wide, and 15 mm deep. The tray wall thickness should be 3 mm and the base thickness should be 3 mm. Add four internal screw bosses inside the bottom tray. Each screw boss should be 8 mm outer diameter with a 2.6 mm pilot hole. The screw bosses should be located 9 mm from each outer corner and should align with the lid holes. The lid should be a separate flat part, 95 mm long, 70 mm wide, and 3 mm thick. The lid should have four through holes with 3.2 mm diameter. Add counterbores on the top of the lid: 6 mm diameter and 2 mm deep. Add a visible seam between the lid and the bottom tray. Keep the cable entry slot on one short side, 12 mm wide and 5 mm high. Make the housing suitable for FDM 3D printing.
