You can get professional precut rounds of the mesh material from TJ's tackle and just a guess from your video 2" -2 1/2" bed??? Just take a picture with a ruler near the opening and for that size you're talking $2.50-$3.00 hardly that expensive. I've had some of the flexible mesh given to me and tried to get more from McMaster Carr, I couldn't match the mesh size. Course with 9 cups for my small and three for my large I'm set.
