Before I discovered the inserts for screwing 3D printed parts. I would just walk My screws are right in the plastic dies. Although it held, removing and reinserting the screws eventually cleared the hole in the parts. After finding and using insoles, I knew I would never go back. Although the usual soldier tip will do. Using these tips will help hold the inserts in place when pressed directly, allowing your parts to fit together more precisely and your finished 3D printed designs to look and feel much more solid. I will definitely get a set.
