A homemade snoot was an easy find. I used the plastic hydraulic piston covers from a computer chair I was disposing of. Just unfastened the clip located at the wheel base and the piston was easily removed. They slide together tight and fit the flash well. The light port is able to be used directionally. Some similar slip covers from another chair i found were not formed as well. it would require tape or glue to hold them together so they were slated for another project..
Here are three shots I made today with the new snoot along with an image of it on flash.
