I cannot find the measurements for the filter tray of the Fotga DP3000 Matte Box like this:

I have contacted several sellers but they have no idea.
If you have the same filter tray, can you please measure the outer width, height and also thickness so I can see if it will fit my matte box.
Thank you.
