I like a hole for a washer with a pin. But if someone really need to have a tooth, make it bigger and then file it to specific size. Laser unable to do very small teeth (they are melting at the tip).
But the reason I like those extra locking holes - my panel is a sandwich (aluminum base + fiber carbon overlay). And I don't make locking holes in the carbon fiber panel.
