The first 3D printed BEmask design was a derivative of the Montana Mask created by  Dr. Dusty Richardson, Dr. Spencer Zaugg and Colton Zaugg. Their work is licensed under a non-commercial open source license. Material has been modified from the Version 1 from their website.

The Harbec Mask was inspired by the BEmask design. The BEclear mask is derived from the Harbec and BE Mask designs, and was also inspired  by the Mayku Mask.  

These 3D printed masks have not been fully tested and have not been approved by federal or state authorities.
