Inspired by the famous EVA project, I designed this for my BIQU BX and the BIQU H2 extruder in combination with the ebmpapst RLF35-8/14N fan.

But since most people use a 5015 fan, I also designed a module for this popular fan.

And for those, who need more “POWER”, I included a module for a dual 5015 fan mount. ;-)

5015 blower fan
5015 blower fan dual
5020 blower fan (https://a.aliexpress.com/_EQFLN7v)
7530 blower fan

Neoteck
Adapter plate for BIQU HERMIT CRAB
Holder for KUSBA
Tool Head for BIQU BX for PCB “Hotmode V2.0”

CHANGELOG

Feel free to test it.

mad_onrail_ebb42_updated.stl

04.09.2023 Update - wider openings

02_MAD_DUCT_3-v001--TRIHORN-export.stl

23.07.2023 New Duct for the 3DO nozzle cam with larger outlet

the cam: https://github.com/3DO-EU/nozzle-camera
the mount for Biqu H2: https://www.printables.com/model/450006

The mount is fully compatible with the MAD system

06.03.2023 Toolhead for BTT EBB42

Added MAD_ON--EBB42.stl (beta test) → testfile

!!!!! As this is an early beta - please be careful, and check the hight of the bolts to avoid short circuit !!!!!
