Custom Piece Miniature – black FAST Future Assault Shell Technology style tactical helmet – 3D Print for LEGO minifigure

Here’s a description of the item in the image:

The item is a black tactical helmet designed for minifigures. It is specifically identified in the filename as a “Fast helmet,” which refers to a common modern combat helmet style (Future Assault Shell Technology). The helmet in the image has a sleek, somewhat rounded shape with integrated or attached elements that resemble goggles or a visor frame around the front eye area. It also appears to have molded details that could represent accessory rails or mounting points on the sides and top. It is shown fitted onto a flesh-toned minifigure head.

Based on the Chinese text in the file name “【K27】黑色Fast头盔”:

• 黑色 (hēisè) means “black.”
• Fast头盔 (Fast tóukuī) directly translates to “Fast helmet.”

The “[K27]” in the filename appears to be the model number or product code for this accessory.

So, this item is a black FAST (Future Assault Shell Technology) style tactical helmet for minifigures.
