WCIF Empty Bookshelf

The dilemma of being a collector in Sims 4 is that it's hard to find a place to display the frogs. In Sims 3 I could just stack the terrariums on top of each other, but not in Sims 4. I've tried some mods that made it so bookshelves would add object slots, but none had a big enough slot for the frogs. I really like the look of the bookshelf in the picture here for this mod, but the creator didn't make it big enough to hold the frogs and look right (you can put them there, it uses up both slots on the shelf, but it only graphically displays on one side, leaving the other side looking empty...rather an odd and unbalanced look). I was wondering if anyone has created something similar to this style with big enough slots for the frogs (and it could even be something like a display case, shelves, bookcase, table, etc)?
