I know there is lots of good discussion about the underlying causes, but I wanted to talk about the 3d printed part of your question. I describe my experiences in the attached post, but the TL;DR is petg and abs broke quickly if they were used for the tabs. What worked well was having a TPU insert to get squished. You will have to experiment with your slicer settings. (My post talks a bit about what worked for me.)
Of course this was all done before avid had come out with their solution, which is likely better than my 3d printed one.
