This is an override that adds seven small deco slots to the top of the Maxis “All-Purpose Desk”. It looks like it should have some there, but by default it doesn’t.
Overrides the _RIG/RSLT 0x0D004129DE6C3B67. Note that when the desk is against a wall (which it often will be) you’ll need to turn on moveobjects for many items to fit on there, since otherwise the game thinks their footprint is too large and would clip into the wall. Same for large-ish items when they are closely spaced.
