LS piston ring squaring tool

Here's a piston ring squaring tool I designed for a 4.8/5.3 LS engine. This is a helpful tool for getting the rings square in the bore and even across all cylinders for when you're gapping the rings so you can go out and turn the boost up to party and scare old people without breaking your ring lands… again

you can also scale for other LS engines

6.0 scale to 105.80%
6.2 scale to 107.50%
7.0 scale to 109%
(If you're building an LS7, you probably aren't using this tool LOL)

Also, I added finger holes so you can remove the tool from the cylinder, this allows the tool to print flat on the pad without having to add supports for a handle
