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 time No supports 2 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.
