Technology Will Save Us DIY Gamer Kit (£35)
The Technology Will Save Us crew want to get people engaged with technology and encourage experimentation – and their latest DIY gadget is a doozy.

Up! Plus 2 3D printer (£1620)
This Christmas, why not make your own gadgets and turn your house into a microfactory of the future? The Up! Plus won our 3D printer group test in the September issue of Stuff, delivering "the best results of the printers, quietly and consistently." Its successor adds automatic platform levelling and height calibration to the mix, which should make for even more impressive chess pieces, toy robots and other plastic trinkets.
