A pack with 10 lakes, all they fit in a 200x200mm printer bed, the largers models are already sliced in smaller parts.
Tips to get a good result:
print them with 0.3 layer (it will save a lot of time)
choose the water color base depending of the enviroment that you want. (Blue, green, brown)
Apply lighter shades on edges, next to the rocks and where you will add some vegetation,then blend it gradually
add the vegetation as you want.
apply 2 or 3 layers of liquid resin. BUT, remember to wait it drys completely to apply the next layer.
you can drop some leafs,moss or similar between layers to look like failed leafs or underwater plants.
Have a nice game and feel free to sell printed models.
