Black Widow Heatsink Cooling Duct with Light and BLT Mk4
This duct is a revision of the previous versions and has been reduced in weight. The Mk3 is pictured mounted but Mk4 stl file is available here. Will update description when I have some extra photos.
This duct is designed so that the heatsink is provided with maximum cooling even using lower powered fans. The BLTouch is mounted 45mm from the centre of the extruder so it will clear the "Evolution" series of layer coolers. This means that it will also compatible with most other types of layer coolers. Use a 40mm fan.
For best results, use a 24volt 3014 series LED as pictured. wire the LED to the same circuit as the fan, this will not only light up the extruder for you but will indicate when the hot-end is hot and the fan is on.
BLTouch offset:
32mm right
32mm forward
A spacer for the BLT has also been provided if using "Volcano" heatblock.
