LS1 Piston Ring Compressor 5.7L 3.898" / 99mm

Fixed-size ring compressor for 99mm bore engines/pistons. Save the $35 dollars on a tool you will use a handful of times and print this. NOTE: I suggest orienting the print with the center axis of the cylinder perpendicular to the print bed. If you print in that normal orientation, the piston rings tend to catch on the later lines.
