These are rear bumper dome caps designed to fit the following truck models:

Toyota Tacoma 05-15

Toyota Tundra 00-06

This is to replace Toyota part number PT22834000BK

Note that I did kind of wing it on some of the dimensions, and they fit very tightly. They could probably be scaled a bit in X and Y, though I printed them as-is, and they worked. The little legs are NOT designed to be flexed. You should compress the whole housing to get it seated. I usually put one leg in place, and then push on the other side to pop it in. You can then rotate it so the logo is facing the proper direction.

I printed mine in black CC3D PETG at a 0.2 layer height. I also did a test print in PLA which seemed to work fine, but I'm not sure how well it would hold up outside in the long term. I used a support blocker so that I'd get a small amount of support only on the legs, and nothing else (see pictures).
