My only comment is that you are unlikely to get your new drawer pull to aesthetically match the others. The finish will probably not look right. You may be better off trying to fix the broken one. There are some newer adhesives, specifically "structural Cyanoacrylate" that are really quite good. And with a surface treatment chemical, even plastics bond well. But, of course, none of that would be as fun as 3d printing.

Consider modifying the design of the pull and replacing the pulls in a certain portion. Perhaps just the top drawer pulls.

But, as you already noticed, drawer pulls are vulnerable to being broken by collisions. Around 20% of the ceramic pulls in my kitchen have broken or come out from its metal stud. If you use your rapid prototype system, you may want to design it to be fairly thick for strength and use heat-set inserts for the fastener.
