Customize Hard-to-Find Fittings

Struggling to find a 62mm to 48mm connector or a 3" port adapter? Using our interactive form with real-time preview, Dust Fit lets you dial in the exact dimensions, taper angle, wall thickness, and more—giving you total control over your setup.


Print Your Own Parts

Dust Fit allows you to generate STL files tailored to your dust collection system and download them instantly. Use your preferred material, control your costs, and avoid waiting for shipping. Once you've bought your part, you own it and can access it anytime from your account. Need four elbows? Only pay for your parts once and print as many as you need.


Test Before You Commit

Not sure if your fitting will match? Print a slim tester ring with the same dimensions to test the fit first — no wasted filament, no full reprints. Generate as many testers as you need to ensure a perfect fit for free before you commit to buying the part.
