Citadel paint holder, with brush or tool slots in the back. The front edge of each holder is designed to display the names as clearly as possible (see: Leadbelcher). Each brush or tool slot has a cutout for easy cleaning if things get messy inside; it also helps fit The Army Painter triangular brushes. This model has gone through numerous iterations to improve print time, and reduce material cost— although your mileage may vary depending on your settings.
