Creality Ender 3 v1 3d printer. Wasn't called v1 because there was only one version but they've released several models since then. It's a bare bones kit, no bells and whistles. No auto leveling. No run out detection. I had to add thermal runaway myself. I absolutely love it. I love difficult things.

I did get it a big brother a few years later. (sovol SV06 plus)
