Thanks for this update. I still have the 8-inch rail version that I bought just prior to the release of the i3v. It's still working great and I use mine pretty much the same as you, now and then, and often big lapses of time goes by. It still prints very clean and beautiful parts. I've made a few upgrades as well. One is a "leveler" that I posted on this site and get 4 or 5 downloads a month. The other was a dial head design called the Itty Bitty (designed by @Clough42). Like you, I print only one material, but I use PET.

I'm glad to see your iv3 is still going strong.
