Ultimaker 3 Auxiliary 12v Power

[pa9k 4]

Hello.

I have built a acrylic enclosure for my 3 extended. I want to add a fan to it to circulate air through the printer when printing PLA. I was wondering if there is a hookup on the board for auxilary 12v power, and what kind of power it can handle. The fan I am going to install draws 0.45A or about 5.5w.

Of course I can use an external power supply for the fan, but it would be nice to cut down on wires.

I don't know the answer to your 12V question - but keep in mind that the provided power supply is already scratching at it limits (at least during dual printing). 0.45A in addition could be too much (better safe than sorry...)

This is kind of what I expected. Do you have specs on the power supply in the printer?
