How to Reassemble the Das Keyboard 3 Ultimate

For those who care

I recently tried to clean my Das Keyboard, but got stuck at reassembly. Looking online, I found no solutions. I got some guidance from the Das team on Twitter, but no precise solutions. So I managed to piece it together myself.

From the above picture, you can see that there are keys with R1 for the first row, plus dpad and period on the numpad. R2 includes the numpad and the special keys (highlighted in yellow, embossed with dashes and a period respectively from left to right). R3 includes the Del, End, PgDn buttons, and the top of the numpad. All the other keys have various numbers written on the back, and as far as I can tell, can fill any of the remaining spots. The other differently shaped keys should be self-explanatory, or at least easy enough to figure out.
