A custom-made Kanohi Mask designed and modeled by yours truly. I couldn't have done this without KingSidorak, who printed the mask for me using FDM 3D printing.
The Kanohi Tridax, Mask of Animation, allows its user to grant any non-organic or non-living object sentience, with the user able to define how cognizant the object is. This mask is one of a kind, and is currently in the possession of a Toa of Iron.
