Custom Piece Miniature – ACH Advanced Combat Helmet style helmet olive green – 3D Print for LEGO minifigure

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

The item is a military-style combat helmet for minifigures, presented in an olive green color. It has a classic, somewhat rounded shape that covers the top and sides of the head, with cutouts for the ears. There’s a visible molded detail on the front, which appears to be a mounting bracket, likely for night vision goggles (NVG) or other accessories. The overall design is consistent with an ACH (Advanced Combat Helmet).

Based on the Chinese text in the file name “【K57】橄榄绿ACH头盔”:

• 橄榄绿 (gǎnlǎnlǜ) means “olive green.”
• ACH头盔 (ACH tóukuī) translates to “ACH helmet,” where ACH stands for Advanced Combat Helmet.

The “[K57]” in the filename appears to be the model number or product code for this accessory.

So, this item is an olive green ACH (Advanced Combat Helmet) style helmet for minifigures.
