What it is
A magnetic quick disconnect sized for 2.5 inch shop vacuum hose. Swap the hose between tools without twisting cuffs.
How to measure
Measure your magnets (diameter and thickness) before exporting, and measure the hose. 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 matching polarity per half and test the pair before the glue sets.
- The “To buy” list shows how many magnets to order.
Frequently asked questions
- What size should I measure?
- Measure your magnets (diameter and thickness) before exporting, and measure the hose. 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.
