MNT Reform Standalone Keyboard V3 Stand?

Hello,
I was wondering if there is a stand available for the Reform Keyboard?
In the review by Wolfgang which is linked on the keyboards store page, it says that there is a stand included in the package. However this does not seem to be the case in the current models, even tough the chassis has the mounting holes for the stand to screw into.
Since I am working from a new location the keyboard is just a little bit less ergonomic than it would be in a tilted position.
Is there anything available, maybe an STL or something to DIY such a stand?
