I used the flange on the bottom of the lid - the bit you get your nails under to get it off the box. Customer wanted to see the sides of the lid (after being told he could if he thought that would look better)
An anally accurate CMC cut reverse bevel rounded corner mount slid over the lid and sat on the flange. At the back it was a simple sink mount. Centre photo shows a test cut.
This could be done with a rectangular aperture manually, you’d just need to do something nice underneath the small exposed bits at the corners.
