I think that I used my MK3. I spent around 350€ when I bought the parts from China, but if you buy the kit from Prusa it's around 800 bucks!
Regarding your other comment, I think that you should be able to print this with 0.1mm layer height. The threads are difficult for the printer, so in my case I had to screw the cap on and off multiple times. Every time it went a bit further until in the end I could completely screw the cap on.
