Full tray that holds up to 32 bottles of Vallejo/ArmyPainter standard bottles. Each has a bit of a wiggle room and fits into the chest. Prints without supports, I've used Fat Dragon terrain print profile, but default one should work well.

I'm thinking about collapsible racks for them, so you could store everything in the chest, but also pull it out and use it as full-fledged paint rack. For now – just a rack.
