The prompt

Create a flat rectangular adapter plate for a doorbell. Overall dimensions: width 115mm, height 185mm, thickness 5mm. Corners should be rounded with a 6mm radius. In the exact center, add a circular hole with a diameter of 25mm for cables. Add 4 corner mounting holes (diameter 4.2mm) arranged in a rectangle that is 98mm wide and 164mm high, perfectly centered on the plate. Also add 2 smaller vertical holes (diameter 3.2mm) with a center-to-center distance of 63.5mm, aligned vertically and centered, for the Blink doorbell mount.
