This is a near-as-can-be replica of the Kara Kesh (also known as: Goa'uld hand device and Goa'uld Ribbon device) from the stargate SG-1 series, made based upon a relatively small left hand and multiple images from various web pages.
Some artistic changes were made, both due to shape of arm it was designed for, and due to what looked most correct.
Unlike the versions in the series, this one is left handed, but that is easily fixed, should you want to do that. (reversing along one axis)
Arm it was designed for is not included.
