I guess it depends on a “ship of Theseus” type of a thing. Sure, I’m technically using a 2018 first gen Ender 3, but it also has linear rails, a Phaetus Dragonfly with a Bondtech CHT nozzle and BMG extruder, a BLtouch and it’s running Klipper with input shaping, and as a result it can spit out an almost flawless not-a-speedbenchy (because I have a 0.6mm nozzle running 0.3mm layers so it doesn’t qualify) in 22 minutes. Only thing missing is that I still haven’t upgraded the main board or stepper drivers as I’m not bothered by the noise.

So it’s both 5 years old, and also better and more moderd than quite a few of the models provided by Creality today.

I have an old prusa i3 mk1 that I’ve converted to a laser engraver, it no longer 3d prints but is still useful in a new way

I am officially retiring my Wanhao i3 Duplicator v2 on Friday when my BambuLabs p1p arrives.

Well… sort of. I am stripping the i3 of parts and I am going to use them to start building a Voron 0.2. Most of the parts are junk, but I should be able to re-use the motors, the SKR Mini e3, and a few other items/upgrades from the i3.

My stock Prusa i3 MK2s from 2017 is still in regular use & still works great. Not sure if this counts as ‘old’.

I’m still using my Ender 3 that I got in 2018, but I’ve been slowly upgrading it. Right now it’s got BTT SKR 3+raspi+klipper, a magnetic PEI build surface, direct drive extruder, dual Z (but I’m going to switch to the belted z mod by kevinakasam with a single Z stepper, partly so I can use the endstop phase feature of klipper to increase Z accuracy.
