Do you find parts that you download and print that are suppose to fit together don't?
I have 3 clones that had me convinced designs needed slop to fit together. Then I got my Prusa MK3 and discovered it was my printers and you don't need to add slop to a design. That was great news, as well as disappointing because it meant my other printers were almost worthless to me since I mostly print parts.
I've rebuilt the clones upgrading them piece by piece and it seems the MK3 extruder is the difference but I am still testing.
Does anyone have insight on what causes, and how to deal with parts that don't fit together? The most obvious clue is holes that are too small.
