Review: Great for projects - I used this to place a metal screw thread into a 3d printed piece. This piece is actually going to be subject to heavy vibration and screwing into direct plastic would cause a failure. This solution is perfect! The screw gripped onto the threads and secured the two pieces of 3d printed plastic tightly. If I tighten too much, the screw felt like it would strip out before damaging the screw thread. This tool was so easy to use and very strong. I definitely recommend this and see myself using this on many more projects, other than 3d prints. It's very versatile.l!
