This is a trash bag holder for the front door pockets of a 2024 Chrysler Pacifica.  Print with your choice of heat tolerant material.  It fits standard plastic disposable grocery bags or any similar bag and allows you to place trash down in the door pocket next to the seat.  It completely tucks away next to the seat when the door is closed.  You place the bag up through the inner ring, fold it down and clip it in place with the outer retaining ring.  Then you plug the riser into the bottom of the ring and clip it onto the edge of the door pocket.  This allows the bag to fill the bottom of the door pocket and expand out into all the irregular spaces.  The original files are in Tinkercad and I have made them public if you want to tweak the riser for the geometry of your car (search Pacifica Door Garbage Bag Holder).
