| It might be just as easy to drill a grid of holes and file them out with a square file. You can get white metal ones but for your model I would expect you to want to make them from wood.
I think probably the most realistic though would be, as you say half cut through matches at appropriate intervals. I'm sure if you laid them together and cut across carefully with a blade it wouldn't be too much of a chore.
