Nokia has started to offer a set of printable 3D backs for its Lumia 820 smartphone, according to a report from Engadget. Customers are able to download the files from Nokia’s website and either forward them to a printing service or bring them into a store to get a (somewhat) unique made-to-order case.

The snap-on cases harken back to one of Nokia’s most popular phones of all time, the Nokia 5110, for which there was an endless supply of snap-on faceplates sold at innumerable mall kiosks. Nokia is now calling itself “the first major phone company to begin embracing the 3D printing community.”

Customers who download the printing files (free Nokia developer account required) can forward them to online services like Sculpteo or Shapeways to get a single print in a color of their choice. As for retail options, Staples now provides 3D printers along with the rest of its print, ship, and copy arsenal in its brick-and-mortar stores.

While this seems like a bit of a gimmick for the middle-of-the-road Lumia 820, it makes us eager for the day when we can print-to-order cases for other smartphones, maybe created by DIY enthusiasts who aren’t backed by a manufacturing operation but are handy with Maya.
