Electronics Enclosure Shell with Display, Drawer and Servo Lock

Create a rectangular electronic enclosure shell. The overall outer dimensions are 110 mm wide, 90 mm deep, and 160 mm high, with a uniform wall thickness of 2.5 mm.Add a solid horizontal internal floor exactly 40 mm from the bottom base to divide the enclosure into a lower drawer chamber and an upper electronics chamber.On the front face of the upper chamber, subtract a rectangular cutout 44 mm wide and 59 mm high, centered horizontally and positioned 70 mm from the bottom base, to mount a 2.4-inch TFT display.Directly below the display cutout on the front face, add a hollow cylindrical tunnel protruding outward by 10 mm. The cylinder has an outer diameter of 22 mm and an inner hollow diameter of 16.5 mm to act as a breath guide for an MQ-3 sensor.On the back face, subtract a 9.5 mm wide by 4.5 mm high rectangular cutout located 42 mm from the bottom base for a Type-C TP4056 port. Add a 3x3 grid of 2 mm circular holes on the upper back face for a 3W speaker grill.On the internal horizontal floor (the separator at 40 mm height), subtract a 23.5 mm by 12.5 mm rectangular hole positioned near the back wall. This allows an MG90S servo motor to be mounted facing downward, so its single-direction arm can rotate into the lower chamber to act as a locking deadbolt. Remove the bottom front face of the lower chamber entirely (below the 40 mm floor) to create an open cavity for a sliding drawer.Fillet all outer external edges of the main box with a 3 mm radius to give it a sleek, modern tech gadget aesthetic.
