These are some wonderful 3 tier fountains that are 3D printed and ready to paint. This listing is for 1 fountain.

The micro fountain will work for 1/144 scale
The small fountain will work for 1/48 scale and will be a smaller fountain. 
The large fountain will work for a larger fountain in 1:48 or a smaller fountain in 1:24.

The photo of the She Shed shows what the small fountain looks like next to a 1:48 structure.
