Easy to Print & Assemble Design
The CQB Helmet features a seamless multi-part design that makes for a much easier printing, painting and assembly experience. The entire helmet can be assembled without the need for glue so you can test your final helmet before using any permanent adhesion methods.

There are multiple versions of several files to allow for optional build configurations. This helmet has a large opening such that the typical magnetic neck seal is not required, but is included as an optional file set anyway. Additionally, there are versions of the largest pieces, pre-split for smaller printers.

The CQB Helmet comes with built-in side speaker support as well as overhead and side fan/ventilation compatability. All can be powered via a large compartment in the rear of the helmet, large enough for a AA battery bank and more!
 
Alternate open versions of the external ports exist for additional ventilation
