Important notice: a lot of people have been very happy with this product, but, as can be read in some of the comments below, it's clear that this design is right on the edge of what Shapeways can produce to the right quality at this moment. If you buy it, there's a risk of having a less then perfect fit, colors can be different from what you see on the screen, and, depending on how you use your phone as well as the tolerances of the case, it has been reported that the polyamide material can give a sort of polishing/scratching effect on the metal rim of the phone (you can find descriptions online of how to remove these kind of blemishes, but it may still be annoying).
Shapeways has, in my experience, been very good with customer service on this item, so they'll be happy to either return your money or provide a new product if you would be one of the unlucky ones; but it's up to you if you want to run the risk that you may have to go through this process.

Essential protection for iPhone 4S and iPhone 4

Even though 4-4 may be the worlds lightest and smallest iPhone 4 case, it still provides great protection to the vulnerable edges of the iPhones' front and back covers - while all controls and connections remain accessible. Its slightly protruding profile helps prevent protect the glass when laying your phone down; using 4-4 can also help to avoid signal loss problems.

This bumper-style case may be combined with commercially available screen protectors. 4-4 is manufactured from tough and durable 3d printed polyamide; it has a slightly textured surface that gives you great grip on your phone. Available in white, black and limited edition colors - note that in white, the 3d printed material may get dirty more quickly - but you can (seriously!) dishwash this product, so that shouldn't be too much of a problem. The 4-4 case is designed to have a tight fit around for iPhone. To put the iPhone in the case, or take it out, start at one of the bottom corners, where there are no buttons. Colors in the images above are for reference only; please check under 'select material' to get the most up-to-date preview of currently available product colors. Product is shipped in basic Shapeways packaging.

4-4 fits the GSM and CDMA/Verizon versions of iPhone 4, as well as the new iPhone 4S.

A two pack of 4-4's in the same color is available at reduced prices here.

You can have a look at all the products in my shop here. Consider buying 4-4 together with The Wrap, a handy cable winder for the European iPhone charger.

The first 3D Printed iPhone 5 Bumper designed to account for differences in outside temperatures that can make other 3D printed bumpers looser and tighter.

HeatLock is designed to be too small for your iPhone 5, which may sound strange, but is actually a revolutionary concept. As the bumper gets hotter, the plastic nylon it is made out of will expand, causing the bumper to get bigger. If the bumper starts too small for the phone, you could heat it up enough to get the case on, then as it cools it will fit perfectly.

When your case arrives simply heat it up with a blow dryer or heat gun for a few seconds to expand the plastic. Slip the case on and allow a few minutes for it to cool off. The case should shrink down so that it is snug to your phone.

Prototyping is complete! Model will fit very snug on an iPhone 5 after heating!

Using your bumper:
1. Unpack from box
2. Heat corners of bumper
3. Stretch onto iPhone
4. Keep heating and stretching until bumper fits
5. Enjoy!

To undo case, reverse process. iPhone will not be damaged by added heat; however, Shapeways nor SolidWorks Tech Designs assumes responsibility for any damage done to your iPhone.
