What it is

Adds a small port for a manometer or pressure sensor so you can measure suction in a duct.

How to measure

Measure the outside diameter of the existing duct or hose; the clamps, sleeves and liners are sized from it.

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.
• The “To buy” list shows the purchased hardware it needs.

Frequently asked questions

What size should I measure?

Measure the outside diameter of the existing duct or hose; the clamps, sleeves and liners are sized from it.

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.
