3D model description

Super high air flow efficiency dual 5015 fan duct upgrade for Ender 3 S1, S1 pro, Sprite extruder and a included CR-BL Touch no Y offset mount

  • This brand new duct design will give you an amazing 6mm of
    clearance from the bottom of the nozzle. Not only from the front
    but from both sides for an all around perfect visibility, and
    completely avoid the duct hitting our parts when printing.

  • Fully compatible with my other design. Now you have more
    options. Going from 2 duct design, dual 5015 fans, 3 duct design
    single 5015 fan. It's your choice, you can mix and match

Link to my other design:

  • The newest design of the ducts have been adjusted to completely
    redirect all the high pressured air flow to the printed part.

  • This new design will not only allow you to set the right height, but
    you also will be able to make small adjustments on the angle of
    the ducts from front to back to slightly redirecting the airflow if

  • This dual 5015 fan duct design will allow you to do your always
    wanted high speed printing, and even with the added weight still
    be able to get great quality.

High Speed Benchy
24mm layer height in 24 minutes
20mm layer height in 27 minutes

Duct are spaced apart enough to give you the option of using a high flow Creality kit and may also save you the need of having to print the ducts on a high temperature filament, but it still recommended.
( I do not have the high flow kit, this was based on their online specs but I am sure it will work)

I included a light version of No Y offset mount that is compatible with both of my designs. It allows you to install it, and remove it easily without the struggle of having to remove your extruder just to install it.


All the pieces need to be oriented to be printed on their flat surface. No supports are needed

The No Y offset mount is the only part that needs supports

Ducts need to be printed in PETG or a high temp filament.
The rest of the parts can be printed in PLA.
