my version for a direct drive dual extruder. for my mendel max.
Work in progress, design files are available for whoever is interested.
motors fans and e3d extruder models were taken from grabcad.
Consider moving the extruder fans so they do not blow hot air from one extruder onto the other. Just the first thought that jumped to mind. Free advice is worth what you pay for it. LOL
I thought about that too but i figured out that i use the e3d extruder which supposedly can handle without active cooling. And in addition when the fans blowing from opposite direction it will result hot air blowing to the part which may be not that bad. I guess when i start printing i will find out…
You can run the fans in the opposite direction and draw air across the heat sinks. Maybe with a divider between the sinks so only cool air gets drawn.???
Sounds interesting. I will test it. It will not be complitly cool but heated a bit by the heatbed but may be iteresting.
