Compact . low profile PCB Clip / Standoff

A PCB clip for the corners of boards with no mounting holes and very little free top area
The screws (designed for M3 countersunk) are located under the board for when space is tight. The clips need a small section of one edge to be clear on each corner.

Print on-edge to print without support (and accept some clean-up of the countersunk hole will be needed)
