Spark Plug Compression Adapter Fitting Removal Tool

This may be helpful in getting a 12mm compression adapter fitting off of a Grand Cherokee (WK2). Got one stuck on the 12mm spark plug holes and made this to get it unscrewed. Made with 3 walls and 30% infill. Will need a grabber or something to grab it after it's loose. You might be able to screw a tool into the adapter once loose to get it.
