You may have bought a case to go along with your Kyria, or you may have made your own. These instructions apply to the acrylic Kyria cases for sale on splitkb.com.
Acrylic Plate Case
Carefully remove the protective film that will be present on both sides of the acrylic layers. Put screws through the top plates (with holes in them for the switches), and screw on the brass spacers.
Decide whether you want to use any larger 2u keys in place of other thumb cluster keys. Up to two 2u keys are supported on either half, marked MXa21 and MXa22.
If you choose to use 2u keys, you may choose to use one or more PCB mount stabilizers. Install these before installing the plate as it’s impossible to install the stabilizers later.
Install the switches through the plate, making sure they sit fully seated into the PCB, then solder them. I like to start with a switch near each corner, working my way to the center. Please check each switch whether it is seated correctly before soldering, because it is a cumbersome to fix their alignment later on.
Take care when soldering the switches. There are various pads close to each other. Which ones you'll use depends on the kind of switch you're using. You'll want to avoid forming bridges between the pads as noted by the exclamation mark sign below, as this will cause keys to not work later on.
After you've soldered the switches, you can assemble the bottom of the case. However, you might want to skip along to the next step to install the firmware and test your keyboard, as you'll have easy access to all the joints, to prevent having to uninstall your freshly assembled bottom plate. After you've verified that the keyboard works, you can finish assembling the case.
Before putting on the bottom of the case, you should first install two long spacers to support the OLED window. The screws mount to the bottom of the PCB through the two little holes near the thumb keys, the spacers attach from the top. As the last step, you can remove the protective film from both sides of the window, and mount it to the top of the case, above the microcontroller and OLED display.

Attach the spacers to the bottom layer first using a single screw. Be sure to leave a little space, around a millimeter, between the bottom plate and the standoff. They should sit loose. This is to compensate for any variance in the thickness of the acrylic layers.
With the standoffs installed, slide over the two middle layers, the plate, then the first high profile layer.
Then insert the small pieces near the Pro Micro, and finally place the second high profile layer, followed by the clear OLED guard window. Secure the OLED window using the taller screws, and the rest of the top layer using the smaller screws.
