Found it very annoying to have a bunch of water drip out of the trays after drying - forcing a second dry before storing. This also holds them better - preventing them from falling or sliding down.
Made for the extra large model based on published tray dimensions but currently untested. Please let me know if it works. I am particularly interested in how the XL version fares. I did increase the footprint and placed the CG on center but those trays are huge.
