This one does use a puck light, the specific ones I used and modelled around are here.

You can use any dragon silhouette and just place in the center of the moon and put a little heat on it! It will drop right down flush with the dome. Add a little drop of glue for security.
The back of the nook has a little plug that snaps in, I wouldn't recommend glueing in case you need to pop the light out for some reason. The moon fits snug around the puck inset as well for easy removal.
Filaments used:
Bambu Black
Bambu turquoise (frame)
Bambu Marble (Moon)
Bambu Ice blue translucent (Eggs)
Bambu Brown for the nest
Bambu white for the frame color
