Here's how to create a unique, bespoke case for your iPhone 4, 4S or 5 with Sculpteo's 3DPcase app and 3D printing service.

3D printing is becoming more and more popular, mostly because it's now just about affordable for the average punter.

Paris-based Sculpteo ( can print a variety of 3D objects including vases that mirror the profile of your face, ornaments and whatever else you care to design.

You can also download the free 3DPcase app from Apple's App Store and create a case for your iPhone 4 / 4S or 5.

Prices vary, but expect to pay around £20 including delivery, which takes around four days.

How to create an iPhone 5 case

Step 1. Download the free 3DPcase app and launch it.

Step 2. Tap the button near the top to select the iPhone 5, then choose a case design to customise.

There are three designs for the iPhone 5: Curves, Cross-stitch and Bubbles.

Step 3. We've chosen bubbles. On this screen you can choose from a range of colours. Next, tap the Bubbles button and you'll see a screen where you can tap (or tap and hold) to bend the lines. Tap a point to remove it, or if you'd prefer, simply tap the Case Builder button to go back and start again. You can enter some text at the bottom to finish.

Step 4. Click the 3D view button to see your finished case - you can swipe your finger to rotate it, and pinch to zoom in and out.

Step 5. If you're happy, you can tap the Buy button. Also, note the Save to My Designs button at the bottom if you want to return to the design later, perhaps to print more cases.

Step 6. Check the details and tap the Check out button.

Step 7. Enter your details on the Ship/Bill tab, then choose a shipping mode on the Payment tab. Once the order is confirmed, you will receive and email with your order details.

Our case arrived in four days, and is an excellent fit for the iPhone 5. We wouldn't call the finish 'polished', though. It's a grainy, matt finish which is more like Tarmac than smooth plastic, but it feels tough and protects the phone just like any other shell-type case.

Here's the finished case:
