Last September Nokia introduced the AT&T exclusive Lumia 820, their first Windows Phone 8 device with a removable shell with or without wireless charging (Qi) capabilities. These shells come in trendy colors (red, cyan, yellow, black and white) and can be purchased here.
Nokia has stepped up the customization game once again by introducing 3D Printing kit for Lumia 820. If you have access to a 3D printer, you can create own specialized cover. This link has all the information on 3D printing and it also features a conversation with , a Nokia community & developer manager. John is a great guy we met at a Nokia sponsored Mobile Monday event in NYC last year.
I have contactedregarding the availability of a 3D printing kit for the Lumia 810 and Lumia 822. He says ‘Nokia is starting with the Lumia 820 3D printing kit to gauge demand but more is planned’.
