This is a holder for citadel paint pots featuring 10 slots per tray. Trays can be stacked over each other using the supplied frame. A frame is built for 3 stacked trays. By scaling the z-direction this can be increased directly in the slicer.
The holder itself uses a spring like structure to assure the pots don't fall out of the tray if tipped over, but can be removed and placed easily.
