What it is
A magnetic coupling whose magnets sit around the collar instead of on a flat face, for a slimmer joint.
How to measure
Measure the magnets you bought (diameter and thickness, or ring size) before exporting: the pockets are cut to those numbers plus the clearance you set. For each end, measure the hose, pipe or port it joins with calipers. If that part slides into the fitting, measure its outside diameter and keep “Measure by: Inner diameter”. If the fitting slides into a hose, measure the hose’s inside diameter and switch to “Outer diameter”. Measure twice across the circle; flexible hose is rarely perfectly round.
Print tips
- The export already places every component in its recommended print orientation. Keep supports off sleeves, sockets and any sliding or tight-fit surface so they stay smooth; if your slicer asks for supports, paint them only where an outside overhang needs them.
- Glue magnets with every pocket on one half facing the same way and the opposite way on the other half; test polarity before the glue sets.
- The “To buy” list shows the purchased hardware it needs.
Frequently asked questions
- What size should I measure?
- Measure the magnets you bought (diameter and thickness, or ring size) before exporting: the pockets are cut to those numbers plus the clearance you set. For each end, measure the hose, pipe or port it joins with calipers. If that part slides into the fitting, measure its outside diameter and keep “Measure by: Inner diameter”. If the fitting slides into a hose, measure the hose’s inside diameter and switch to “Outer diameter”. Measure twice across the circle; flexible hose is rarely perfectly round.
- What should I print it in?
- PLA or PETG both work for dust collection at room temperature. Print in PETG or ASA if the air is warm or the part sits in the sun. Use 3–4 perimeters for an airtight wall; infill matters much less than wall count for ducts.
- What hardware do I need to buy?
- At these starting sizes it needs: bolts or screws, washers, magnets. The “To buy” list in the designer gives the exact sizes, lengths and quantities for your dimensions.
- Does it need supports?
- The export already places every component in its recommended print orientation. Keep supports off sleeves, sockets and any sliding or tight-fit surface so they stay smooth; if your slicer asks for supports, paint them only where an outside overhang needs them.
