Win Win Notes:
I CA glue the rail and lens base to the floor and the lamp to the roof.
I printed 'the lens' in a clear filament, the rails in Wood, the base of the lens in a darker contrasting color and the 'lamp' in that same color. Make one and make your mother smile. (that is if she likes lighthouses)
Enjoy
