There’s a great group on Flickr called, “The Art of 3D Print Failure“, that showcases the results of a 3D print gone wrong. The goal of the group is to encourage discussion and “analysis of the failure and ways of preventing such failures in the future”. The site can be quite entertaining in the way a blooper reel is and maybe you can help someone too. Of course you can try to avoid errors all together by following good 3D printing practices like those found here.
