Ever since getting into video production, I've wanted to make these variable ND sunglasses. Thanks to awesome sponsors like PCBWay, we are able to print these in metal, which was so much fun! Check them out here : https://pcbway.com/g/9532T0

They offers comprehensive manufacturing services including PCB production & assembly, machining, sheet metal fabrication, injection molding, and 3D printing.

Filters
( PLEASE MAKE SURE TO ADD UV FILTERS )
This can be done by unscrewing the variable ND filters with a calliper or something similar, and adding some UV glass between the two, on these VND's I use in the video there's more than enough room to accommodate an extra layer, so nothing in the design has to change, pretty awesome! :)
