sorry for the damage! regarding the paint... it is tough to get dead nutz as specified in previous posts... and with color matching, its never going to be a perfect match. hope the expectation wasn't carbon copy of the takara because that's almost impossible. it's very close in my opinion but again, as it's a custom mix to try to color match, it'll never be 100%. and regarding the edge, as they are 3d printed, it's the nature of the parts. any 3d printed part, shapeways part, STL part... there are gonna be imperfections in the surfaces from building. those edges are under a millimeter in size. to try to sand them smooth like the exposed surface would be extremely hard, high potential for snapping off since it is so tiny and ridiculously time consuming. here's a close up of the edge unpainted and the exposed surface. you can see the major difference in the exposed surface in that pic to the final you have from priming, sanding and painting. but that's what it takes to get it smooth like the final. the edges would take forever to get like that working under a magnifying glass. and thats if you didn't break them because everything is so tiny. not an excuse or blowing you off... but it was designed and made to be an inexpensive fix... that makes the gap look better. to totally sand and build the part and make it look injection molded from takara and match the paint 100%, it would be a waste of time as no one would want to pay what it would cost after hours of work on each piece! so again, sorry for the damage, the fix is listed above if you want to try again.
