Table saw safety key

Lost the key to my table saw and needed to make some long rips. Didn't find anything that worked online so I made this, took a few tries but it got there. Not as strong as i would like when printed in PLA, but it works all right.

Feel free to upgrade and let me know if you get it less fragile, or even if there's a better orientation to print it for strength (I have been printing with the small pins in the air, which means the layers line up to easily snap the pins. I'm just not sure how to do it better)
