Cools all sides of your print at once, so your layers stick together better and prints come out cleaner.
Fits snugly into your fan outlet without extra tools, saving you setup time on your Anet A8 or Hessine M505.
Weighs just 12 grams and needs no support during printing, so you waste less material and print faster.
Leaves room for heater and thermistor wires, so nothing gets pinched or damaged during installation.
Comes with OpenSCAD file so you can tweak the design to match your exact printer setup.

Get cleaner, stronger 3D prints by cooling all sides of your nozzle at the same time. This circular cooling duct wraps around your MK8 extruder and blows cool air from every angle, so your plastic sets up right instead of warping or sagging.

The duct is light and simple to install. Just push it into your fan outlet like you would a regular funnel. No brackets, no hardware, no fuss. The design leaves plenty of clearance for your wiring so nothing gets crushed when you snap it in place.

You get the STL file ready to print, plus the OpenSCAD source code. That means you can change the shape, size, or fit to work with your exact printer setup. Works with Anet A8, Hessine M505, and other printers that use MK8 style extruders.
