In the M2.5 fastener set, find 4 each of the longest screw (M2.5×10) and the shortest standoff (M2.5×6 F-F)
Ensuring that the reset switch is positioned below the cutout tab, insert each screw from the front of the bezel, then through the OLED display. Using the stand-off like a nut, tighten the screen in place.
Adjust the rotation of the standoff nuts so that the OLED display can be pressed down onto the headers of the Feather.
If using heat-set inserts
Place the inserts loosely in the holes, with the narrow side down. With a soldering iron heated to 240°C (or the lowest setting available, if it's above 240°C), gently press the insert down into the plastic, keeping the iron in line with the post. Note that this is not perpendicular to the base! If you are using Adafruit's heat-set insert rig one easy way to get the angle right is to print a second enclosure and stack them back to back so that the posts are vertical.

Place the PCB in the enclosure and secure using 4 M2.5×6 screws.
If using the snap fit case
Place the PCB in the enclosure and gently press down until it moves past the snap fit ridges. You can release the PCB by gently flexing the sides of the enclosure away from each other.
Simply ease the caps onto the stems and check that they operate smoothly. For tricky keys like 9 and 6 you may find that you've swapped their positions or rotated them, which leads to the key profile being inconsistent.
