Until 4:00 PM today, March 9th, Verizon and MakerBot are offering free 3D printed smartphone cases as part of Verizon's #WhyNotWednesday promotion. Simply go to the promotional web page, enter your phone number (if you're a Verizon customer) and pick your design, color, and phone model. MakerBot will then print your case and mail it to you for free. Not a bad deal, especially if you're prone to breaking things - a backup phone case is never a bad idea.
