This project serves to learn about the potential of threaded inserts. Given the problem of the fragility of some structures, it is possible to use these inserts to create functional hinges and 3D prints.

The print test shows the various sizes of pre-holes to be created on the new 3D prints

Threaded inserts bought on Amazon but you can buy them on many other sites.

These threaded inserts must be inserted using a 900M or T18 soldering iron.

This is an example of the soldering iron that I used. [https://amzn.eu/d/f6qZP2n](https://amzn.eu/d/f6qZP2n)

These are the most precise tips to use but you can also use regular soldering iron tips.
