Stackable cases for UCS sets

Hey y’all! I want to keep my Lego dust free. So all my sets are currently in the IKEA Billy bookcase cabinets (and I added lighting for cool effect). However, I have several unbuild UCS sets (Falcon, AT-AT, Razor Crest) and am planning on getting the Sail Barge and Venator before they retire this year. These of course do not fit inside the Billy at all, so I’d like to purchase acrylic casing or whatever. It’d be awesome if I can stack them on top of each other. I mean, I’m not a billionaire...
