60mm Magnetic Quick-Connect Duct Coupling — Genderless Snap-Together | Van Life Diesel Heater Vent | Dust Collection RV Camper | 10x5mm Magnets | Hose Clamp Groove

Genderless 60mm magnetic duct coupling that snaps together tool-free and pulls apart in a second. Any half mates with any other half. There is no male side and no female side to keep track of, no orientation to get wrong, and no second STL to slice — you print the same part twice and you have a working coupling. The magnets do the alignment and the holding; you do nothing but push the two halves together.

Each half carries six 10×5mm disc magnets arranged in alternating north-south-north-south poles around the bore. Because the poles alternate, any two halves snap together and self-align no matter how you rotate them — and because the pattern is symmetric, two identical parts are always a matched pair. This is what makes it genderless. It is also what makes the hold strong: six magnets per side means twelve in a connection, gripping in shear and in tension, so the joint resists both pull-apart and the twisting that vibration loves to introduce.

The magnet pockets are deliberately printed 0.2mm oversized. The 10×5mm discs drop in with thumb pressure instead of fighting a too-tight bore, and you avoid the cracked-pocket frustration that comes from forcing magnets into a print. A small dab of CA glue or two-part epoxy in each pocket locks them for the long haul — set the poles correctly before the glue grabs, because once it is in, it is in.

There is a hose clamp groove around the barrel of each half. Slip your 60mm flex duct or hose over the spigot, drop a worm-gear clamp into the recessed groove, and the clamp seats mechanically instead of sliding off under heat cycling or on corrugated roads. This is the detail the copies leave out and the reason their connections rattle loose.

✅ What Makes This Different
- Tool-free connect and disconnect — magnets hold the join; no clamps, clips, or screws to undo when you need it apart
- Genderless — identical halves, alternating-polarity magnet ring; any coupling mates any other and self-aligns
- 6× Ø10×5mm magnet ring — strong, repeatable hold from the most common and cheapest hobby magnet size
- 52mm smooth bore — continuous air path through the coupled join, no internal restriction
- Hose clamp groove — positive mechanical seat on standard 60mm duct at the stub end

🔧 Application Examples
- Van and RV ventilation hoses that have to come apart for cleaning or winter storage
- Diesel-heater ducting that unclips for servicing without tools
- Dust-collection and shop-vac hoses that swap between tools in a second
- Removable vacuum hose fittings on a workbench or in a cabinet
- Any duct run you would rather pull apart by hand than unclamp

📦 What's Included
1× STL file — one 60mm magnetic coupling half, 52mm bore, 6-magnet ring, hose clamp groove, pre-oriented, no supports. Print two for a quick-disconnect pair, or pair with any other DT3D 60mm magnetic coupling. Magnets (Ø10×5mm neodymium) are not included.

🖨️ Print Settings — Read This Before You Slice
The coupling prints flange-face-down on the plate with no supports required. After printing, flip it over and drop the magnets into the now-upward-facing pockets, gluing each in with CA or epoxy and watching the alternating-polarity sequence as you go — a magnet seated the wrong way will repel its neighbour's mate.
Use a 0.2mm layer height, 4–6 walls, and 15–25% infill. PETG or ASA for outdoor and UV-exposed van/RV installs; PLA is fine for indoor dust-collection use. The flat mating face is the first layer, so a clean, smooth build plate gives the best magnet-face finish.
