storage trays on central post

i made these storage trays for my desk to hold various items, it has a central post that holds up to 5 trays the trays have a print in place hinge that i designed ( first time designing a working hinged part ) the trays also have a dovetail locking clip so they cant come undone from leverage from the weight when items added to trays trays could be customised by using the cut feature and cutting off the hinged section and joining it to a tray of your own aslong as the height is no taller than the original trays
