Modular Citadel/Vallejo paint rack- Elevated level

I want to be able to have 2 rows of these Paint Racks and created a raised spacer to be able to place these on top of each other. I have printed these in 0.3mm PLA with 10% infill. Took the help of my friend to fix the file so it was cleaner to print. Remix of: https://www.printables.com/model/94429-modular-citadelvallejo-paint-rack-lite-remix
