105F is about 40C. 40C is fine for PLA. If you do have heat issues, the first solution is to use ABS plastic as it can handle temps up to about 90C. and I hope your motor never gets that hot. They also make a glass-filled nylon that is even stronger when hot and very stiff and hard with the glass microfiber inside.
About printed gears, Make the center to center distance adjustable. I've got a couple module 2.0 spur gears here I printed and it does not seem to matter if there is a 0.5% size error. I just move the spacing by 0.5%. They seem to be tolerant of running with zero clearance too. This helps with backlash.
