This very small mod replaces the static http://static-3.nexusmods.com/15/mods/100/images/43257-1-1409317969.jpgwith a portable item. Because it's, you know, a tray. Trays are for carrying. The "new" item has also been inserted in a leveled list (random_de_pos_01), so it should show up in crates and merchant inventories here and there. Use a leveled list merger!
I've also fixed a large gap on the bottom of the mesh, which is normally not noticeable in-game but might be if you start placing it everywhere or if you have a mod which adds this object in a strange location.
Note: this will not affect instances of this object placed by other mods: they will still be immobile (though the mesh fix is in effect everywhere).
