Guardian 2211-L (TX) car clip

Strictly speaking, I don't think this model needs supports if you print it upside down, but depending on the material you're printing with, that's not the best orientation to print it in. If you're using PLA or PETG, you should print it rotated 90 deg on its side so that the clip is stronger and less likely to break along a layer line. You will need supports to print in this orientation.
