This is a holder/jig for 3" pipe that can be used for making piecuts that can then be welded. You can fasten a piece of sheet metal at the ends and that will function as a stopper. I printed it standing up so it will need some support. I printed mine i PETG and it clamped the pipe really good and the coolant from the saw wont affect the plastic.
