I’ve had a K1 for a couple of years now, and I’ve never had issues getting parts for it. I recently replaced the hot end and hot end breakout board because of my own personal stupidity, and I was able to just buy the parts. And they fit.

Is something different about your or my K1?

I have a 3D printer, and a Suzuki Samurai. More than a few parts for the 35 year old Suzuki have been printed by me.
