Universal Turbo Dust Shoe for CNC router

thingiverse

I'm Boyan, a CNC enthusiast who's been active on various forums. I've spent countless hours perfecting my DIY CNC setup for woodwork, which has given me valuable insights into dust extraction systems. Over the years, I've tried numerous commercial and DIY solutions, but they all had flaws that made them impractical in real-world situations. Product videos often showcase dust shoes working flawlessly with powerful industrial vacuum cleaners, capturing 99% of dust and chips. However, my experience suggests that these scenarios are unrealistic. In a typical workshop setup, I cut out shapes from wood blocks raised on a vacuum fixture, creating the worst-case scenario where chips and dust try to escape through the clearance between the table and work block. This is why I designed the Turbo Dust Shoe, an universal dust shoe suitable for various spindle and hose dimensions combinations. The MKII version incorporates design changes learned from printing different sizes, ensuring improved performance. File names are self-explanatory: "NO" indicates no offset, "ID" means the hose goes inside, and "OD" signifies that hose clamps are attached from outside. Special versions for Roland and Tecnomotor machines, as well as large cutters and facing surfaces, are also available. For custom shoes, please visit cncdustshoe.com. Here's a brief overview of my design process: I started by researching dust extraction systems in various workshops, looking for the most common scenarios where dust shoes fail to perform. I realized that most commercial solutions were designed with ideal situations in mind, rather than worst-case scenarios like mine. This led me to develop the Turbo Dust Shoe, which is specifically designed to handle high and low pressure vacuum cleaners and chip extractors. Key features of my design include: * Excellent airflow for large chips * Hi-volume low-pressure chip extractors won't choke or lose power * Hi-pressure workshop vacuum cleaners work well with it * Even a small home vacuum cleaner can effectively suck fine dust and most chips The best extractor for the job is typically a shop vac with a 2-stage minimum motor, preferably in the 40-60mm hose range. This setup achieves high volume and high pressure, making it ideal for workshops. As you can see from the images, I've tested my design with various bits, including a 3mm bit, 6mm bit, and 12mm bit. The red brush attachment is designed to clear even the smallest chips used in woodworking projects. Here are the print settings I used: Printer: Original Prusa Mk2 Rafts: Yes Supports: Yes Resolution: 0.3mm Infill: 30% Notes: Print with PETG, which is an excellent material for this purpose. Make sure to adjust the separation of raft and support properly on a test piece before printing. I'm confident that my design will meet your needs, and I'd be happy to answer any questions you may have.
