Filament suggestion

[gdgdad]

I'm designing a piece (2 actually) that I need to "snap" together. I printed it with standard PLA, however the PLA is too brittle and the snap "prongs" will not bend. I need a semi-flexible filament with some "give", but not rubbery. I've researched but some are said to be as flexible as gym shoes and can be folded, etc. That would be WAY pliable for this application. I've attached a picture of my design - any suggestions before I invest in a new type of filament? Thanks gdgdad6@gmail.com
