How it works in three steps
Cut a hole in your enclosure for the exhaust port. Many builds use a 4 inch hole.
Match your port size to your duct or fan size. Pick that pair below.
Each end is a friction fit. It pushes on and holds with no clamps in most setups.

Each one is a real part, priced and ready. Pick the pair that matches your port and your duct, then add it to your cart.
Vent to a 4 inch duct
Most enclosure kits use a 4 inch duct. Join, extend, or step down to fit yours.
A small 2 inch port, out to a 4 inch duct.
A 2.5 inch port, out to a 4 inch duct.
A 3 inch port, out to a 4 inch duct.
Both ends 4 inch. Join or extend a kit.
Step up to a 6 inch inline fan
Running a bigger inline fan? These pairs step your enclosure port up to a 6 inch fan.
A small 2 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 enclosure port
The port is the fitting or hole where the air leaves your enclosure. You need its size to pick the right pair.
Measure across the opening, not around it. A tape or a caliper works. Ports vary by kit, so pick the closest pair and measure again before you order.
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.
Common enclosure setups people ask about
Here are sizes people report for popular builds. Use them as a starting point, not a promise.
| Setup | Port size reported | A pair to start with |
|---|---|---|
| DIY IKEA Lack enclosure | you cut it, often 4 in | 4 in Straight Adapter → |
| Bambu Lab X1C, P1S kits | 4 in common, 2 in compact | 4 in Straight Adapter → |
| Creality, Ender enclosures | about 3 to 4 in | 4 in Straight Adapter → |
| Resin printer enclosures | about 3 to 4 in | 3 in to 4 in Straight Adapter → |
These sizes come from maker forums and product listings, not our own tools. Ports change by kit and build. Measure your port before you order.
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 seals 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 enclosure end and your duct end, and we print it to size.
Build your adapterWhat is a 3D printer enclosure vent adapter?
A 3D printer enclosure vent adapter is a short fitting. One end matches your enclosure port. The other end matches your duct, fan, or window vent.
It joins two sizes that do not fit on their own. We print each one in PETG to your two sizes, so the joint is snug with no duct tape.
Frequently asked questions
Do enclosed 3D printers need ventilation?+
Some makers add a vent to send the air outside. Whether you vent is your call. If you do, this adapter joins your enclosure port to a standard duct.
How do I vent a 3D printer enclosure?+
Cut a hole for a port, then run a duct from the port to a window. An inline fan moves the air. Our adapter joins the port to a 4 inch duct.
What size port should I cut in an IKEA Lack enclosure?+
Many DIY builds cut a 4 inch hole, because 4 inch duct is easy to find. Pick the 4 to 4 pair to join it, or step down if your fan is smaller.
Do I need duct tape?+
No. Each end is a friction fit, printed to the size. It pushes on and holds with no tape or clamps in most setups.
Can I use a bigger inline fan?+
Yes. Step a 4 inch port up to a 6 inch fan with the 4 to 6 pair.
My enclosure port is an odd size. What do I do?+
Use the builder. Set both ends and it makes the part to your two sizes.
