What it is
Bolts to a laser cutter or engraver exhaust and steps down to a smaller hose.
How to measure
For a flange, measure the opening it covers and the centre-to-centre spacing of the bolt holes it must line up with. A barbed end goes inside the hose: make its outer size match the hose’s inside diameter.
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.
- Print in PETG or ASA; laser exhaust can be warm.
- The “To buy” list shows the purchased hardware it needs.
Frequently asked questions
- What size should I measure?
- For a flange, measure the opening it covers and the centre-to-centre spacing of the bolt holes it must line up with. A barbed end goes inside the hose: make its outer size match the hose’s inside diameter.
- 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. 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.
