Designs for Hermit Crab Shells from Artist Aki Inomata #3DThursday #3DPrinting

Here is a recent project by Japanese artist Aki Inomata that appears to take up the challenge issued by artist Miles Lightwood “TeamTeamUSA”‘s 2011 Project Shellter: can we 3D print shells for hermit crabs to live in? Inomata pushes the shell design even further — check out details and photographs below:

This project was designed to show at the exhibition, “memento vivere/memento phantasma”, held at the French Embassy in Japan.

In accordance with the relocation of the French Embassy, some buildings of former government offices would be demolished. This land which had been part of France became part of Japan last year, and then 50 years later will be France again.

Inspired by the fact that the land in the middle of Tokyo suddenly and peacefully changed its nationality and the hermit crab’s fascinating habit of moving from one shell to another, I prepared shelters Tokyo house-style and shelters a la Paris appartement for the hermit crabs.
I hoped they liked my shelters and moved into them.

Meanwhile I also tried flower shaped shelters (hermit crab living inside a flower!)
and ones with moose antlers and some others all inspired by the concept of “identity transfer”, the theme throught this project.

Hermit crabs are selective in choosing their shelters.

Therefore, I decided to CT scan and capture the detailed 3D images of the unoccupied sesashell which one of my hermit crabs had abandoned.
Based on those images, I modified and slightly enlarged them with a 3D modeling software, and then produced several types of shelters with a rapid prototyping system. Finallly I gave those shelters to my hermit crabs.

It was their turn to choose their shelters.

Initially I was concerned that they might not be interested in the plastic shelters I had created. However, one day I witnessed one of my hermit crabs moved into my shelter after he had been torn between a natural seashell and my plastic one. I was pleased with his decision, but also had mixed feelings as he chose a plastic shelter rather than a natural seashell.

Every Thursday is #3dthursday here at Adafruit! The DIY 3D printing community has passion and dedication for making solid objects from digital models. Recently, we have noticed electronics projects integrated with 3D printed enclosures, brackets, and sculptures, so each Thursday we celebrate and highlight these bold pioneers!

Have you considered building a 3D project around an Arduino or other microcontroller? How about printing a bracket to mount your Raspberry Pi to the back of your HD monitor? And don’t forget the countless LED projects that are possible when you are modeling your projects in 3D!

The Adafruit Learning System has dozens of great tools to get you well on your way to creating incredible works of engineering, interactive art, and design with your 3D printer! If you’ve made a cool project that combines 3D printing and electronics, be sure to let us know, and we’ll feature it here!
