Bed thermistor went bad at 10,539 hours.

This is now 9 replacement thermistors, roughly every 1,000 hours. I consider it a maintenance item at this point.

Only other failures were a bad stepper bearing at 3,500 hours and the main board failed at 4,500 hours. I didn't bother with the warranty on the motor since it was easy enough to swap bearings but Prusa replaced the main board under warranty.

My second MK3S+ has been flawless. It has had two thermistor replacements in 3,500 hours or so.

I really wish they would make the thermistor wires thicker. I should probably just modify one myself.

Failure #12 at 10,685 hours. Heater cartridge.
