How it works in three steps
Measure across the exhaust port on your machine. Write down the size.
Match your port size to your hose or fan size. Pick that pair below.
Each end is printed to a standard duct size, so it presses on and holds in most setups. Add a wrap of tape at any joint that sees heavy use.
Common setups
Each one is a real part, priced and ready. Pick the pair that matches your port and your duct, then request it and we print it.
Vent to a 4 inch hose or window
The most common setup. Adapt your machine port to a standard 4 inch hose, then run it to a window vent.
A small port near 2 inches, out to a 4 inch hose.
A 2.5 inch port, out to a 4 inch hose.
A 3 inch stock hose, out to a 4 inch hose or vent.
Both ends 4 inch. Join two lengths or add a coupler.
Step up to a 6 inch inline fan
A 6 inch inline fan is a popular upgrade. These pairs step your machine port up to fit one.
A small 2 inch port, up to a 6 inch fan.
A 2.5 inch port, up to a 6 inch fan.
A 3 inch port, up to a 6 inch fan.
A 4 inch port, up to a 6 inch fan.
How to measure your exhaust port
The exhaust port is the pipe or hole where the air leaves your machine. You need its size to pick the right pair.
Measure across the opening, not around it. A tape or a caliper works. Pick the pair that matches your number.
The distance across the outside edge of the port. Use this when your adapter slides over the port.
The distance across the hole. Use this when your adapter slides inside the port.

Whatever your machine, measure its port. Use the builder. Set your machine end and your duct end and we print the part to those two sizes.
Where does the air go?
Run the far end of the duct to the outside. An open window or a wall vent both work.
A window vent kit closes the gap around the hose. Many kits use a 4 inch hose, so a 4 inch end fits right in.
Your size is not listed?
Build the exact pair you need. Set your machine end and your duct end, and we print it to size.
Build your adapterWhat is a laser engraver exhaust adapter?
A laser engraver exhaust adapter is a short fitting. One end matches your machine port. The other end matches your hose, fan, or window vent.
It joins two sizes that do not fit on their own. We print each one in PETG to the two standard sizes you pick, so the joint is snug in most setups.
