I want to try out this (thingiverse.com/thing:845347) design for double part cooling fans on thingiverse. Is there anything I should be wary of when connecting the two fans?
I am thinking that I would just connect the two fans in parallell configuration to the original part cooling fan slot on the extruder board. Do I need to replace the resistor on the extruder board to make sure that both fans still receives 12V?
I also wonder if there would be any signifcant risk for heat creep or other potential problems with the hotend, due to the fan ducts in this design?
