Suitcase Handle PUSH Button for retracting handle

My daughter's Samsonite carry-on suitcase recently broke, the button within the handle broke and would no longer work to allow the handle to retract. This button is simply a length of plastic, and when depressed in the center of the handle then depresses two other buttons at the top of each of the handle shafts.

I printed at 99% infill to ensure a very solid, durable part that can hold up to the stress during usage.

I've included 2 STLs, one of the original design, and another with built-in supports I added via Meshmixer.
