I printed everything in PLA. The heat is no problem, because the parts that touch the PLA are eigther not getting hot at all or are getting cooled. Just make sure that the cooling fan is running all the time a nozzle is hot. All those warnings about not printing parts of the printer in PLA are simply bullshit as long as you are not using a closed case for your printer. If you do so then, and only then, PLA is not a good choice.
