After some feedback from coworkers, I decided to make a v2 that you can leave over the bracket. Still a work in progress. Might make it a tad smaller so it has a tighter tolerance and won't move as much. Any suggestions to make it better let me know! I printed this in PETG since it's staying in the car, but you might get away with it in PLA.

Didn't see any on Makerworld so whipped up this little tool. After fumbling around with a small screwdriver to remove the headrest in my Tesla Model Y to install a babyseat, I decided to just make a simple tool you can keep in the car to help with the removal.

You use the nub on the outside of the tool to first remove the headrest. Then you slide the tool with the nub on the bottom into the slot. When you want to release it, just push in the side with the nub and it should release!
