GM spark plug boot removal tool

I made this tool for my 01 Yukon XL 1500. The spark plugs boots have a heat shield on them and if those boots have been attached to the spark plugs for a few years they can be a pain to remove. This tool works on all the plugs even the ones with minimal space in the back. I printed in PLA and didn't have an issue.

Instructions: Once printed out, slide the open end over the plug wire and expand it enough to slip over the heat shield until the lip settles into the groove. Then take a pair of pliers (I found needle nose vice grips work well for constant pressure so they don't slide off) and something to pry/leverage the boot off.

I plan to make a video of this sometime. I sold my Yukon so I don't have a demo vehicle :(. I plan to get another later on though. I will also be adding this to my Shapeways so anyone without a printer can still get one. https://www.shapeways.com/product/WED3B5S4N/gm-chevy-spark-plug-boot-removal-tool
