I could 3d print a bunch of these no problem for people that are interested. My prints aren't show quality but if you're hiding it, it shouldn't be an issue.
I built in something similar to a custom board that I'm working on where the teensy 2 is just held in place by tabs and it works just fine.
You can kinda see it in this pic:

If you have the need for custom mounting points that is also something I could handle.
