Modular Filament Storage System - V1 (Tested & Reinforced Design)

IMPORTANT - VERSION INFORMATION

This listing represent V1, the main and current version of the system.

An earlier ''Early Release'' version is still included as a legacy option for users who only want a press-fit, tool-free assembly. However, V1 is the recommended version and should be considered the primary product goinf forward.

Note: The first images are renders from the original early-release concept. Real photos of the finalized V1 design are included further down.

Overview

This project is a modular filament storage system designed for long-term stability, scalability and real-world use.

V1 is the first fully built, reinforced and physically tested version of the design. It introduces mechanical fastening and additional structural support to significally improve rigidity compared to the original early release.

Modules can be combined horizontally and vertically using dedicated connectors and rods, without relying on long continuous rods.

The system is designed around standard 1kg filament spools.

Whats New in V1 (Main Version)

V1 introduces several structural improvements focused on long-term strength and stability:

• Mechanical fastening throughout the system

  • Rods are secured to the connectors using screws

  • Connectors are fastened to the feet

  • Connectors are also mechanically fastened to each other is stacked.

• Upper reinforcement rod

  • An additional rod is added to the top between connectors

  • This significantly improved overall rigidity and reduces flex in larger builds

• Improved structural integrity

  • Better load handling over time

  • Especially important for multi-module and stacked configurations

These changes make V1 a more robust and complete design compared to the original press-fit version.

Optional Add-ons (Included)

This release also includes several optional add-ons:

• End caps

  • Inserted into the side rod openings for a cleaner and more finished look.

• Feet

  • Feet for freestanding setups fastened with screws.

  • These may also help support smaller spools (e.g. 250g) by increasing ground clearance.

The system is still primarily designed around 1kg spools. Support for smaller spools is experimental and may vary depending on spool dimensions.

Update March 14th

Added universal labels for filament. Just add text in your preferred slicer. I'm going to add labels for most types of filament in the future.

Printing Notes

The design prioritizes strength and rigidity rather than minimal print time.

Recommended starting point:

• 0.2mm layer height

• 4 perimeters

• 15-20% infill (Gyroid or cubic)

• No supports required

Adjust settings as needed based on material and printer.

Files Included

• V1 - Main version (recommended)

  • Reinforced dsign with mechanical fasteners and upper support rod

• Legacy - Early Release (press-fit)

  • Tool-free, press-fit version included for users who specifically want this approach. This version is no longer the recommended default.

• STL files - ready to print

• STEP files - included for customization, tolerance adjustments or remixes.

Feedback wanted

Feedback is especially appreciated on:

• Fit and tolerances

• Overall rigidity and stability

• Connector and rod interfaces

• Long-term use and expansion

Makes and photos are very welcome!

Planned Future Options

This system is designed to grow over time. Possible future additions include:

• Corner modules

• Wall-mount brackets

• Additional connector variants

• Side-mounted tool holders

• Further refinements based on real-world use
