Feb3.HeliCageArmorWith the growing popularity of 3-D printing, Spin Master offers a custom part for its Air Hogs Heli Cage Armored Edition, a helicopter featuring removable plastic armor. Samples of the part were built using a MakerBot 3-D printer, which creates real 3-D objects by laying down drops upon drops of plastic material and building them from the bottom up. The custom part was also flight-tested by engineers and tweaked for weight balance.

Spin Master now provides an open source 3-D file of the armor part online at the Air Hogs blog. Makers can download it for free and print it using a 3-D printer. For those who do not have direct access to a 3-D printer, Air Hogs recommends Sculpteo, which will print from the 3-D file and ship the part to customers. For the very technically inclined, the 3-D file can be fully manipulated to create a truly customizable piece.
