About this 3D model

These steampunk goggles are designed to use 52mm photographic filters as lenses. I used cheap ND8 filters from dx.com which cost about $6 each. The auxiliary lenses with the sweet orange coating were salvaged from a found pair of cheap binoculars. The strap is a makeshift solution - made from black fabric tape (somewhat like duct tape) folded over on itself. A strap with a bit of stretch would be an improvement.
