Upgrade your workspace with this modular markers organizer, perfect for home, office, and professional 3D printer sellers! Designed for both practicality and style, this scalable organizer keeps your pens and markers neatly arranged while offering a fully customizable setup.

This design features a two-part system:
1. A bottom base with plus connectors, allowing multiple bases to connect seamlessly.
2. Pen holder parts that slide perfectly into the base using VVVV-shaped grooves for a secure fit.
Each pen holder includes 12 marker or pen slots, and each bottom base accommodates up to 3 pen holders, allowing for a total storage of 36 markers or pens per unit. If more space is needed, the bottom bases can be linked together using the plus connectors, making it infinitely expandable for any workspace.
