This is the rubber grommet/mount that fits on the bottom of the AC condenser and fan, where it mounts into the chassis. These are NLA from Nissan and fairly hard to find by themselves. You'll want to print it out in TPU. I printed mine on a Purse i3 mk3s+ in Fillamentum Flex 98A and it was a bit on the hard side, so I'd consider going softer if you can.
