This is a paint holder custom sized for Citadel Colors. It holds all sizes of the Citadel Color bottles except of course the primer spray cans. It can hold up to 4 paints per model and can be hung on the wall. The paints are held at a slight angle to make removing and replacing the paints easier.
As much as I liked all of the other paint holders out there they either were way too complicated. Or they were too big and would take longer to print than it took me to use an entire bottle of paint. These print relatively quick and you can print multiple per bed. They print very well on smaller printers as well. They are a bit on the small side, so if you own a ton of Citadel paints you will definitely be looking for another holder.
Aspire to outgrow this holder! Print four of them and just keep telling yourself "I will soon need a larger, more capable holder. One that maybe isn't as well designed, but far more capable."
I will see about releasing another version of the same holder than allows you to join them side by side so they can be extended. There is always super glue ...
Have Fun! :D
