Check out the glass transition temperature of PLA, that's why it's not suitable for stuff on your car dash ;-)
After 3 year I have never had the spindle get even remotely warm even when I once found the water pump to have stoped, it hardly rises above ambient temperature and im quite often doing 8h tool paths however it no suprise as it only cutting polystyrene so not exactly working hard. Should it ever become a problem I'll just print it from something else. I have actually thought of a new idea to improve it and to work with the cable support so I will probably swap this one over but I will still just use pla it's more than adequate for the job on this machine
