ASUS have just released FreeCAD and 3D source files for you to print out embellishments and useful add-ons for your ASUS motherboards, graphics cards and peripherals such as the ROG Spatha.  Below you can see a 3D-printed finger rest addition to the Spatha, just one of the possibilities this new program opens up.

Certain motherboards such as the Z170 Pro Gaming/Aura sport mounting points specifically designed for 3D printed parts, or you can use empty M.2 mount points as the designs ASUS have made available use the same screws as you would use in an M.2 port. 

You could add a nameplate, an additional fan mount or even extra plastic shielding, in whatever colours you have available to print with.  ASUS chose to use FreeCAD to design the parts so that you do not necessarily need a 3D printer yourself, services such as ShapeWays can print the parts out for you.

If you have SLI or CrossFire bridges that need sprucing up, they have designed covers to snap over your existing parts as well as cable combs to keep your cables under control.  The current designs only scratch the surface of what you could create and add to your builds and you can bet ASUS will be adding more possibilities in the coming months.  You can just add a little something to make your machine unique or go all out with modifications, just check out the designs and see what grabs your attention.
