Campaign Complete — Still Available to Back!

This quick-lock modular system started because I couldn't find what I needed for my own garage shop. I didn't want to compromise on my dust collection, but nothing on the market—commercial or 3D-printed—checked all the boxes. So, I designed these fittings to completely meet my own standards. They’re built to work better, swap faster, and finally solve the headache of workshop dust management.

Design Highlights

• Integrated locking connector option (no added hardware)
• Self-orienting magnetic quick-connect plates
• Zero-pause printing and tool-free assembly
• Universal metric and imperial compatibility
• Fully interchangeable connector plates (no more male/female sides)
• Complete 4in (100mm) and 2.5in (60mm) systems
• Expanded adapter ecosystem and stretch goal accessories

Available Options

Choose from 2.5" (60 mm),  4" (100mmm), or the complete set of connectors depending on your needs. Adapters available to use both sizes together!

Reasons to Back

• Quicker, more reliable tool changes
• More affordable (print dozens from a single spool of filament)
• Fully modular and expandable
• Designed for durability and repeatable use
• Repairable — reprint individual components instead of replacing entire fittings

• Optimized for printability with minimal post-processing

   

What You Receive as a Backer

When you back the project, you receive:

• Connector System files
• Complete Adapter Plate Library
• Stretch Goal Accessories (Dust Hood, Hand Wand, Floor Sweep)
• Printing & Assembly Guide (with part numbers and Bill of Materials)
• Access to future revision updates

This is a fully developed, community-driven system ready to print and put to work in your shop.

If you’re ready for stronger, smarter, and more modular dust collection, welcome aboard.

🚀 The Next Evolution of Modular Dust Collection Fittings

Let’s put the 3D printed dust collection fittings game to rest!

Built on the success of my original fittings — and fueled by the incredible feedback from makers who’ve printed, tested, and offered improvements to them — it’s time to take things to the next level.

I want to move these designs from “just another 3D printed fitting” to the hands-down best dust collection fittings you can buy – regardless of how they’re made.

Built for Makers, Hobbyists, and Small Shops

Whether you’re a maker, hobbyist, or small workshop owner working with 3D printers, CNC machines, laser machines, woodworking tools, or otherwise - you know the struggle:

• Hoses that don’t quite fit across various tools
• Connections that pop loose mid-cut
• And commercial fittings that cost as much as a whole spool of filament — or more

And to add, traditional dust-collection hardware is surprisingly expensive, and outfitting an entire setup can quickly become a major burden for small shops. This project changes that.

The Modular Dust Collection Fitting System delivers a more accessible, affordable, and better-designed solution — a customizable, 3D-printable ecosystem that makes your shop cleaner, safer, and more efficient.

With just one spool of filament, you can produce numerous connectors — saving money, enabling upgrades, and giving you the flexibility to evolve your setup over time. No more hunting for mismatched adapters or spending hundreds on proprietary parts.

The community response to the first generation on MakerWorld has been incredible. Makers around the world have downloaded, printed, and adapted these connectors to fit their own setups — proof that a well-designed system can be both open-source and professional-grade. But it does show clear signs of a first generation product line… it’s now time to evolve.

Introducing the Next Generation Modular System

This isn’t just an update — it’s a complete re-engineering of the system, built for performance, precision, and universal compatibility. I have printed my first prototype of the new connector, and it is wildly satisfying to use. 

Here’s what’s coming as an improvement to the first generation:

• 🔒 Stronger Locking Feature
  Upgraded from four lugs to five for even greater retention and smoother engagement — a rock-solid connection that clicks together with satisfying precision.
• 🧩 Improved Printability
  Every curve, lug, and interface has been optimized for smoother, faster prints with less support and tighter tolerances. I'm pushing to develop a design with no pauses during printing for manual intervention of magnets and nuts - there is currently 3 for the existing generation connectors! All components will be able to be assembled after printing, so you can feel free to “set it, and forget it"! In addition, I will keep a strong pulse on reducing post-processing to a bare minimum - if at all. 
• ♻️ Reduced Unique Components
  Streamlined design means fewer unique parts — increasing interchangeability, simplifying your setup, and making future expansion easier than ever.
• 🌍 Universal Fit — Metric & Standard
  Whether your setup uses metric or imperial components, this system just works. One design to connect them all, globally. 
• 🔄 Expanded Adapter Plate Ecosystem
  More plates. More compatibility. Mount to tools, quick-change panels, or custom builds — the possibilities are limitless.
• 📏 A Whole New Scaled-Down 2.5” (60mm) System!
  Maybe one of the most common requests, this compact version will be perfect for smaller shop vacs and portable tools and expands the system’s reach while maintaining full modularity.

💡 Why Crowdfunding?

The first generation was powered by passion and shared with the maker community. Now, with your support, we can transform it into a refined, best-in-class modular system that rivals commercial fittings — while remaining open, printable, and community-driven.

Your backing will help fund:

• Prototyping and durability testing of the new locking mechanism
• The development of the 60mm Connector Line-up
• Refinement of universal metric/imperial geometry
• Production-quality printable models and documentation
• Expanded adapter ecosystem

🛠️ Join the Movement

If you’re a maker, woodworker, or tool tinkerer who loves clean design and better shop setups — this is for you. Together, we can create the most adaptable, reliable, and 3D-printable dust collection system ever made.

Let’s make sawdust without the mess.
