The prompt
Update this bracket: 1. Total height change to 18.8 mm. The top face (PCB contact surface) outer diameter remains 24.1 mm. 2. The top surface has a large centered rectangular cutout for the sensor; the rectangle extends close to the outer circle edge, no material in that sensor area. 3. Only the top section of the bracket has two 2.5 mm M2 holes for fixing the PCB. These holes are shallow blind holes, they do NOT go all the way down the full 18.8mm height. 4. The bottom side of the bracket has an internal female thread bore, thread diameter 25.3 mm for mating with the lens. 5. Add tapered/stepped neck transition between the top 24.1mm PCB seat and the bottom 25.3mm thread section. Minimum wall thickness 1.5mm, watertight solid for FDM 3D printing.
