HCA: Hermit Crab Association

In my company we have a 3D printer, but I've never tried to render a shell with it. But thanks for the idea anyway. Once I managed to fix my gmail, I will write to my boss and try to experiment on that.

I not only decided to change the furniture and room decoration of the tank, but I must do something in the room where the crab itself is located. Because my last crab ran away and my son was very upset.
