What it is
Many laser cutters and engravers have a 150 mm exhaust flange, while hose and fans are often 100 mm. This adapter bolts to the machine and steps down to a barbed hose end.
How to measure
Measure the machine’s exhaust opening and its bolt pattern, then the inside diameter of your hose. The barbed end goes inside the hose.
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.
- Use 3–4 perimeters for an airtight wall; infill matters much less than wall count for ducts.
Frequently asked questions
- What size should I measure?
- Measure the machine’s exhaust opening and its bolt pattern, then the inside diameter of your hose. The barbed end goes inside the hose.
- 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.
