Looking for case ideas for rtym + faderfox mx12 controller

I’m trying to find a case for my Rytm and my MX12 so I can have them positioned with the mx12 on the bottom and the rytm on the top.

Basically the configuration on his home page http://faderfox.de/home.html

I’ve found a Gator case that is close, but want to see if someone has a great solution I haven’t found.

I want to be able to keep units in the case while playing, and just plop on the cover when done… basically like a dj mixer case… but they are all too big or wrong proportions…
