MakerWorld Description

This rear extension module was designed as a direct expansion for the already released Modular Filament Storage System.

The goal was to create a lightweight and efficient way to scale the system without needing to print another complete front holder.

The honeycomb structure significantly reduces material usage while maintaining rigidity and a modern technical look.

Perfect for workshops, print farms, desktop setups and modular storage walls.
