Nicdular Tray System

I had a very limited dry kitchen space and wifey wanted me to store the oven shelves of Ninja multi use oven and Panasonic Multi use microwave oven and i couldn't find a ready to use models so i came up with the modular type of shelve organizer which can be stack or mounted from top. (i will add in the standing modules and also the adjustable width mechanism). Fell free to let me know your experiences. All the modules are snap to fit and do not need any additional parts except if you are planning to mount it to something (currently only top mount is added).since the length for the rail is too long i break into 2 parts but slot into each other nicely for assembly. let me know if any of you want the un-cut version. tried to think of various scenarios and tried to add as much modules as I could, again feel free to let me know if any of you want special sizes or spacing.i am just a regular guy who like to create something useful for people.
