Summary The other day I dropped my keys, and the loops to hold my key fob onto the key ring broke. So instead of having to buy a new one, I thought why not print one. It is a little big compared to the normal fob, but it shows how you can put 3D printers to some good use. Hope that it helps you out some. (and it fits the ford key fob incase any others are sized differently) UPDATE: I guess this is what I get for using inches instead of the metric system. My files on thingiverse appear to be super small, since I created them in inches on solidworks i saved them in inches when i made the STl file. However, PLEASE let me know if you would like a larger file and i will change the settings for the STL and upload the new file and have a new extension on the file name to tell the difference between the two files.
