You'd better put that coffee down before you exhale it through your nose. Why? Because thanks to the very kind folk at Cartridge Discount, you could win a 3D printer. A second generation Cube by 3D Systems, to be precise. Not only would this make any tech-lover's Christmas, it solves your shopping woes too -- now you can print those socks for Uncle Alan if you win. Or stock up on bargain toner from Cartridge Discount if you don't. So, undoubtedly this is one heck of a prize for our UK readers (sorry everyone else), but you're likely wondering what you need to do to take part? Well here's the best part, just head past the break, read the terms and conditions (important!), and choose from the assortment of entry methods we've laid on for you. Don't thanks us, thank your lucky stars.
