This model is a simple, abstract depiction of two koi in a pond, circling a couple of lily pads.

Again, simply turn the crank and watch them swim!

Printing

I printed everything on three different plates.

The first one is for mechanical parts where precision is not all that important. I combined all mechanical parts into one object, except for the lily pads, to give them a different color without having to swap colors for each layer.

The second one is for the lids, which use adaptive layer heights to make the water ripples a bit smoother, without making the entire print take too long
