Partitioned Pen Holder

I needed an adaptable container for art supplies depending on my current project. This is a simple pen/marker or general purpose container. The container supports 1 - 4 sections for flexibility.Layer height: 0.20+ to save timeNo supports2 walls + 20% gyroid should be strong enough.3mf is from OrcaSlicer using Sunlu PETG. PLA works as well.Included extra pen holders in the .step file.
