3D Printing Model: Clog-Proof 4" Woodworking Dust Collection Blast Gates

🪚 A Woodworker's Best Friend

If breathing sawdust is a woodworker's worst enemy, then quality dust collection is their best friend.

And if you buy cheap Powertec blast gates from Amazon then they'll get clogged with fine dust and you won't be able to close them all the way, your dust collection system will lose suction because you won't be fully closing off branches, and you'll be breathing in sawdust again.

😵 Cheap blast gates suck! And not in a good way!

I tried and hated every cheap blast gate option from Amazon. They sell two varieties: (1) too expensive, and (2) cheap but you get what you pay for...

Instead of buying metal blast gates for $17 each, buy this model and print as many as you need!

📝 Designed for 4" Sewer Pipe and Flex Hose

Sewer pipe is a common choice for hobbyist woodworkers when building dust collection because it's cheaper than PVC (same material, thinner walls), plenty sturdy for the job, and usually in stock at most Lowes and Home Depot stores.

These blast gates were designed specifically for 4-inch sewer pipe and 4-inch flex hose, so you can hook these up any way that works for your shop. They assemble with 1/4" nuts and bolts.

🫁 Save your lungs, get clog-proof blast gates!

These blast gates are clog-proof and self-cleaning. I've been using them in my own shop for years and they are absolutely heavenly! 🥰

👩🏻‍🔬 You have a 3D printer, right?

In order to use these files, you'll need a 3D printer. The minimum size print bed capable of printing these models is 190mm by 210mm. I printed mine in regular old PLA and they work great.

👷🏻‍♂️ Installation advice

I recommend connecting these to sewer pipe with 3 or 4 small screws (I used 1/2") evenly spread around the pipe to make the connection strong, and then sealing the seam with aluminum tape. Depending on the tolerance of your pipe, you may or may not get an air-tight friction fit. The tape may not be necessary, but it won't hurt!

🚙 You wouldn't download a c̶a̶r̶ blast gate, would you?

This purchase entitles you to print as many blast gates as you want for your own use. You may not share or re-sell the files, and you may not sell printed blast gates. In those cases, please direct people back here. If you want to buy pre-printed blast gates, I sell them on etsy.
