Saab 9255845 (Failed Design)

I have redesigned this part a BUNCH for over four hours, but to no avail. This is a failed design, for now...

I'm still having issues with breaking of the prongs, so Printer beware! I've found that PLA+ isn't strong enough, ABS is strong but too messy with my settings currently, and ASA won't work altogether. I'll keep tweaking things till I either get it to work, or give up on it.

Note: The insert piece is best printed long side flat!
