About this 3D model

this is the first concept of an universal filter holder for your camera. in this model you can mount cokin P series (or similar) filters,actually for a wide angle view i choose to mount just 1 filter. the filter holder doesn't need adapter ring for your lens, it fits every model and diameter of lens from 55mm to 89mm. you need only 2 screws with 6mm diameter. this is not definitive, more fixing are coming soon. share if you like it.
