Shelf that works with Song of Ice and Fire Tabletop Miniatures Game

I recently got into Song of Ice and Fire miniatures game. Like really into it. Suddenly I have hundreds of new miniatures to store and display. I made these little shelves to hold them in their unit trays.

I've reduced the amount of plastic used as I iterate, but this version (v6) still uses about 250grams. I'd like to reduce that further.

A couple of notes:

- Prints in one piece without supports - lay it so that the big X on the back is on the print bed

- Has rails that hold the trays loosely

- You can move the shlef (carefully) while it is full

- The trays are meant to stick out from the shelves. I wanted to see as many of the models as I could. Uses less plastic, too.

- Fits infantry and cavalry trays

I've included a new version (SongShelf7) that is the same basic design as 6, but uses less plastic. About 200 grams for this one. I made the main walls a little thinner and cut out more of the floors and back-stops.
