I've made this totally over design case with gasket mount for this lovely macro pad PCB that the Rookey is, please feel free to print and share, and eventually think to tip !
You will need to add poron foam to the plate for the mounting, see pictures for detail (3mm foam), and also screw insert M2 as you can also can see on the pictures.
