I have a Prusa I3 clone printer. It works well but I want a second smaller printer and specifically I want it for these reasons (in order of importance)

1) It will be used for smaller mechanical parts, machine gears, linkage parts, things that would fit in your hand.
2) need to print all types of plastic, ABS PLA and whatever,
3) accuracy and finish quality matter. It must beat an I3 type printer by a noticeable amount.
4) after #2 above print speed matters.
5) cost maters, A "kit" is fine, I have time to research, order parts and build, how long this takes is not important.

I think a mini size delta printer with quality parts might be best. I don't know what to look for in hot ends, linkage parts and so on. I'm likely looking for "high end" all the way around. What I need to the names of stuff to Google and some links
