Custom Piece Miniature – gas mask with dual side respirator filters dark sand – 3D Print for LEGO minifigure

the item is:

• A gas mask designed for LEGO minifigures.
• It is dark sand colored with some black or dark grey details.
• The design features what appear to be dual side respirator filters (the circular parts on the cheeks, painted olive green or a similar muted tone) and a central, possibly detachable, filter or voice diaphragm piece (shown separately to the right in one image).

It is difficult to provide an exact “model number” in the way LEGO assigns them to official parts, as this is likely a custom-made accessory produced by a third-party company that specializes in creating LEGO-compatible elements, often for historical or military-themed creations. The “SKU-01” in the filename is a stock-keeping unit number used by the seller/manufacturer, not a universally recognized LEGO part number or model name.

Therefore, it is best described as a custom LEGO-compatible gas mask accessory in a dark sand color.
