I was looking for pretty much exactly the same thing. After hours of looking with not much luck, I found this one for sale at a decent price from America.

Ultimately it doesn’t have the all-important drawer for straps and cufflinks etc, but I really like the modern design so i’ve persuaded a friend of mine who’s handy with woodwork to make one to a similar design, albeit incorporating a drawer. Will post on here once it’s done. I could always share the designs and specs if you know someone who’s similarly handy.
