What it is
A rectangular flange that bolts over a cut-out or fan opening in your enclosure wall and transitions to a 100 mm hose barb. Combine it with a window insert to send fumes outside.
How to measure
Measure the opening in the enclosure panel (width and height) and the inside diameter of your hose. The barbed end goes inside the hose, so set its outer size to the hose’s inside diameter. Mounting holes and bolt spacing are in Connections.
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: air from a heated enclosure softens PLA over time.
- A thin foam gasket under the flange seals better than tightening the bolts harder.
Frequently asked questions
- What size should I measure?
- Measure the opening in the enclosure panel (width and height) and the inside diameter of your hose. The barbed end goes inside the hose, so set its outer size to the hose’s inside diameter. Mounting holes and bolt spacing are in Connections.
- 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.
