We need a lighter version of the AN/PVS-31 Binocular Night Vision Device (BNVD).
Some considerations you must keep in mind:
Distance between axis and between ocular to axis must remain the same.
Battery case must be the same.
Everything else is suitable to be redesigned.
If we choose your 3D render, we will start a collaborative work with you and send you detailed stl files to be used.
