I was at the plastic shop yesterday to get some material and I noticed this sample. Note that the tabs have a kerf at each edge, this creates a spring like fit and helps reduce the tolerance needed to get good tab fits.
I had never seen this technique before and thought I would share.

Hmmm…I’m not exactly sure what I’m looking…Did they undercut those small shoulders to each of those tabs? And how did they do that?

They cut a kerf in each edge of the tab. They told me that it was part of and app (??) they bought.
