You might even be able to have one made with a short tabs that you could bend to clip onto the case, this would be similar to the buku caps, but at $20 for 3 and a metal one would in theory last longer than a plastic one and it would also be thinner and if you could stamp them it would be much cheaper. for that matter you could possibly machine one identical to the buku from an alloy instead of a plastic, but the cost would probably not be as cheap.
