If you’ve ever bought a pet hermit crab, then you may remember also having to buy several sea shells with it. This is because the crabs don’t have shells of their own, and instead have to find empty shells from other creatures and use those. As a hermit crab grows, it’ll need to upsize to larger shells, hence the need to supply it with multiple choices. Unfortunately, every empty shell gathered for the pet trade is one less for the wild hermit crabs to move into. In places where the beaches have been picked clean, the crabs have reportedly resorted to using things such as bottles and shotgun shells. That’s where Miles Lightwood’s Project Shellter comes in – he’s hoping to design 3D printed shells for use in the pet industry, and is seeking ideas from interested artists and designers.
