Parametric Hollow Electronics Enclosure

Create a hollow rectangular MAIN ENCLOSURE box with an open top. Outer dimensions are 95 mm wide, 75 mm deep, and 125 mm high. Wall thickness is 2 mm. On the front face, subtract a rectangular TFT SCREEN CUTOUT 35 mm wide and 28 mm high, centered horizontally, with its bottom edge 75 mm from the outer bottom base. Subtract four 3.2 mm circular SCREEN SCREW HOLES arranged in a rectangle 53 mm wide and 30 mm high, centered around the cutout. Below the screen cutout on the front face, add a hollow CONICAL SENSOR FUNNEL protruding outward by 10 mm. At the front face, its inner diameter is 16.5 mm. It expands outward to an inner diameter of 26 mm at the open end. The funnel wall thickness is 2 mm. On the back face, subtract a rectangular TYPE-C PORT CUTOUT 9.5 mm wide and 4.5 mm high. Position its bottom edge exactly 5 mm above the outer bottom base (this creates a 3 mm vertical air gap above the 2 mm inside floor). On the upper half of the back face, add an internal circular SPEAKER MOUNT RING protruding 5 mm inward, with an inner diameter of 51 mm and an outer diameter of 55 mm. Inside this ring, subtract a grid of 3 mm SPEAKER EXHAUST HOLES passing through the back wall. On the inside bottom floor, add a rectangular BATTERY FLOOR LOCK ridge running horizontally. It is 10 mm high, 2 mm thick, and 60 mm long, centered horizontally, and positioned 30 mm from the front inner wall. On the inside of the front face, add a horizontal rectangular BATTERY TOP OVERHANG protruding 10 mm inward. It is 2 mm thick and 60 mm long, centered horizontally, and positioned exactly 21 mm above the inner floor to lock over the battery with a 3 mm air gap. On the inside of the left side panel, add four cylindrical ESP32 STANDOFFS extending 10 mm inward. Each standoff has a 6 mm outer diameter and a 2.5 mm pilot hole. Arrange them in a 21 mm by 46 mm rectangle. In the four top inside corners of the box, add four vertical cylindrical LID MOUNT PILLARS extending downward by 15 mm. Each pillar has a 6 mm outer diameter and a 2.5 mm vertical pilot hole.
