Berlin designer Ronen Kadushin has made a conceptual, open-source, contraceptive intrauterine device from a one-cent coin.

His design is published under a Creative Commons license so that anyone can download and adapt the production files.

In normal copper IUDs metal ions dissolving from the device act as spermicide, so Kadushin's fictional design involves a rapid-prototyped holder for the copper-coated steel coin plus a piece of nylon thread.

He hopes that making the files available for collaborative development will lead to a working version, undermining the control pharmaceutical firms have over the price and availability of their products.

While a normal IUD costs hundreds of dollars, Kadushin's prototype costs just €1.25. Download the production files here or order a prototype here.

Kadushin is a champion of open design and past projects include a chair to be "hacked" and an open-source mallet for smashing up iPhones. Watch him talk about open design in our movie on Dezeen Screen.

Here are some more details from Kadushin:

Bearina
Open Design IUD concept

The intrauterine device (IUD) is the world's most widely used method of reversible birth control for women. But as their production and common materials cost only a few cents, they are sold for a staggering 400$- 850$, unreachable for many women, especially young ones.

The Bearina IUD is a political product. It demonstrates the disruptive potential of 3D printed Open Designs to give free and global access to essential products, and circumvent industries (such as the Pharma industry) that aggressively defend their intellectual property to control the price and availability of their products.

As an Open Design, the Bearina IUD promotes collaboration and free sharing of knowledge. Further developed by a networked community or in partnership with a forward-looking pharma company, it is always available for experimenting with and improving, and could evolve into a functional IUD.

The Bearina, with its bear head image, is visually friendly, to appeal, so to speak, to younger women. It is a conceptual product, a design fiction, and absolutely should not be used as an IUD. Nevertheless, it is designed according to dimensions, materials and shapes commonly found in IUDs.

You are welcome to download the production file of the Bearina IUD from my website (.stl- Creative Commons at-nc-sa 3.0 lisenced). It is free and ready for 3D printing. But if you prefer, you can also download it, or even order some Bearinas from Shapeways.com. They are only 1.25€ each.

In copper-containing IUDs, metal ions dissolving from the device create a spermicidal action. To do precisely that, a 1€ cent coin (copper covered steel) easily snaps in the plastic 3D printed part. An additional piece of nylon string is tied to the bottom part to complete the assembly of the Bearina IUD.
