Review: The Solution for Strong and Durable Threads in 3D Printing - The kit comes with a variety of sizes to fit different holes and the brass material provides strong and long-lasting threads. I highly recommend this kit to anyone looking to add durable threads to their 3D prints.
Review: Use a soldering iron - The best way I have found to install these is with a soldering iron. If you are installing these in a blind hole you might have to cut the tip down to install them. These worked great for me but I have only used them in pla and I imagine they would work just as well in petgnor abs.

### ⭐⭐⭐⭐⭐ Use a soldering iron

### ⭐⭐⭐⭐ They are What They Are
*by P***P on January 15, 2021*

A little hard to orient these perfectly vertically even with a press. But they are very cheap and it is possible. I have found these useful in early non-load-bearing 3D printed prototypes where I don’t want to throw down the 30cents or more per fitting of better quality inserts. A slight chamfer to the exterior of one side would make these infinitely easier to seat properly. Other brands I can get to seat straight by hand with just an old soldering iron.
