What it is

An inline section with a hinged lid, for clearing clogs without taking the duct apart.

How to measure

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.
• Moving parts print separately; keep their sliding and turning faces free of supports and brim so they move freely.
• The “To buy” list shows the purchased hardware it needs.

Frequently asked questions

What size should I measure?

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?

It depends on the options you choose. The “To buy” list in the designer shows exactly what your sizes need.

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. Moving parts print separately; keep their sliding and turning faces free of supports and brim so they move freely.
