Our community workshop router table also ends up being a work bench much of the time. A router has been broken in the past by someone accidentally knocking a screw in the hole which landed in the router motor housing, then later turning on the router - crunch.
Since then I have used a small wood cutout with a magnet on one side to prevent this happening again, but its difficult to take on and off and is easy to lose.
Basically the goal is to easily/quickly plug the hole, make it removable, and ideally keep the plug from being lost.
Anyone have a better suggestion?

I think that's your problem right there, unfortunately. There's a lot to be said about having a dedicated workbench. – grfrazee Feb 23 '16 at 14:33
