This is a remix of the ford/lincoln key fob found on Thingiverse to fit my friend's F150 key fob, which had a wider emergency button. It was designed from scratch, only using the original model for reference dimensions since I'm lazy. I've included the fusion file, which was thrown together hastily, but might be handy if you want to make the loop thicker, use a different logo, etc.
The author remixed this model.
The original model had an emergency button that wasn't wide enough for the key fob that came with older f150s. I used the original to get reference dimensions, but otherwise, designed from scratch. I redesigned it to be friendlier to fdm printing, eliminating supports. The original had very thin retention sections, which I've thickened up for easier printing and less layer cracking potential.
