Mazda undercarriage 5.5mm diameter plastic nut

thingiverse

Noticed part of my Mazda 3 hanging loose when checking underneath the car. One of the plastic nuts had come off its mount. I designed and printed a replacement, now sharing with you in case the same situation occurs :). The hole diameter is approximately 5.4-5.5mm, though it should flex slightly to accommodate slightly larger or smaller bolts as well. This part is not load-bearing, but it should work fine for undercarriage trim.
