Blew all your money on a 3D printer and now you can't afford to join the next-gen console war? Don't let that stop you, warm up some PLA and print your very own tiny two-inch Xbox One! It even includes a tiny Kinect sensor to talk to (which is not required for normal console operation).
UPDATE (4/19/2016) - added the STL for the controller, and a PDF with stickers.
Designed on OpenSCAD. Printed with Makerbot Replicator 2 on Zen Toolworks PLA.
Print xb1_blueray.stl in white plastic, and spray/paint it silver.
Print the other parts in black plastic.
To build the Kinect sensor, glue the foot into the indentation at the bottom of the sensor body.
To build the Xbox One, simple glue the blueray piece into the slot on the console body.
Now connect it to the internet and download the 3GB day one patch.
