This project makes use of the intricate geometries and flexible behaviours that are possible with 3d-printed polyamide - holding 111 five-eurocent coins firmly in place to create a stunning necklace. E 5.55 is currently available as a DIY project. Start saving coins now - it’s half the fun. Alternatively, many banks can provide you with those rolls of 5 eurocent coins that you need, at a small cost. A fully assembled version of E 5.55 will be available from michielcornelissen.com soon. Mail me at michiel(at)michielcornelissen(dot(com for wholesale possibilities. Copper can oxidize and become darker over time - which can actually give a great look. If you prefer lighter, shinier coins, there’s an easy - and fun! - way to clean them. Snap the coins out of the necklace, and submerge them in vinegar (you can add table salt, too) for a few minutes. Stir well, to make sure plenty of vinegar gets everywhere. Rinse the coins in hot water, and dry them. It’s magic. The necklace itself can be cleaned with water and soap and even dish-washed, after removing the coins. Each product ordered is individually manufactured, just for you. If you are new to the Shapeways site: to order, you'll be asked to create an account (it's easy; you can even log in with Facebook or Twitter). Product ships in basic Shapeways packaging.
