For your hobby/model painting ease. The center cup holds a Dixie cup for water or thinner. The six smaller cups hold disposable plastic shot glasses available at the grocery or dollar store. Store your brushes in the center cup. The cap is designed to fit over a shot glass to keep your mixes fresh for a few.
I haven't actually printed this version yet, but it is merely a 6 mixing cup version of the 4 cup version I do use in the picture. I use it all the time, so it is very handy. It's useful for mixing paints for the airbrush too because you can lift out the shot glasses and pour what you need into the airbrush then set it right back in the holder so it won't spill.
I made it bigger because I regularly fill up all four cups in the one I made for me.
Hope you find it useful too!
