My original Průša i3 mk0 has been going for 11 years now. It did receive a mk1 upgrade at some point when 3mm filament was getting scarce.

The IEC heatbed connector melted twice. But it’s been solid since I replaced it with an XT60.

Looks like I’m finally getting some metal fatigue in the heatbed temp sensor. I’m considering a new printer. The rest of the components are probably close to giving out after all these years.
