Magnetic quick-release for dust extraction
Magnetic dust collection fitting: detach and reattach your vacuum hose in a second.
One part stays fitted on each machine (sander, saw, planer, laser), the other sits on the vacuum hose. Bring the hose close and the magnets close it by themselves, already centred. To switch machines, pull it off. No hose clamps, no adapters falling on the floor.
Each part is printed to measure for your hose and your tool port, even when they have different diameters: the adaptation is built into the part itself, in metric sizes.
Design yours in the configurator
How it is made
Two parts in PETG (or ASA for outdoor use). The neodymium magnets are sealed inside the plastic during printing: you can't see them, they can't fall out and they don't rust in the dust. A lip on the machine side sits in a recess on the hose side and keeps the joint aligned, so the airflow meets no steps.
Sizes: all parts of the same size fit each other
The face of the coupling (flange, lip, magnet positions) depends only on the size, not on the hose. Buy the pair today and, six months later, a machine side for another tool, even with a different port: if the size is the same, it fits.
| Size | Machine side up to | Flange | Magnets per side |
|---|---|---|---|
| S | ports up to about Ø 40 mm | Ø 71 mm | 6 × Ø 8 × 3 mm |
| M | up to about Ø 68 mm | Ø 106 mm | 4 × Ø 12 × 3 mm |
| L | up to about Ø 114 mm | Ø 152 mm | 4 × Ø 12 × 3 mm |
The hose side can have any diameter: it adapts to the hose within the same part. The configurator picks the smallest size that works; if you already have parts from us, choose theirs.
What you can buy

Magnets included. The configurator shows the exact price: it depends on the diameters and on any bend.
Ready sizes to start from
They are a starting point: measure your tool port and your hose with a caliper and correct the size in the configurator.
Don't want magnets? There's a bayonet version
Same sizes, same prices. Instead of magnets, the machine side has a spigot with 4 lugs and the hose side a socket with 4 slots. Push in, twist 40° and feel the click; twist back to release. It won't come off if you bump the hose, and it prints without pauses. In the configurator, under "Quick release", choose "Bayonet". Bayonet parts only couple with other bayonet parts of the same size.
Questions
Does it hold if the hose pulls? The coupling is designed to stay closed with the hose resting or hanging near the machine, and to come apart with a firm pull. If the whole hose hangs from the coupling, add a clamp or a hook to carry its weight.
Is it suitable for water? No: it is for air and dust (extraction, laser engraver fumes). For water use a fixed fitting.
Can different sizes be mixed? No: S with S, M with M, L with L.
