This is a lens filers for the Nikon B500, insert whatever film or filter you wish, pieces slide together but I use glue to keep everything in place (Do Not glue to your camera). this part will fall off if you aim at the ground, this was a quick build with a slightly too large clearance

Made this for the Solar Eclipse so I could put a solar filter on my camera without using a rubber band.
