## Customer Reviews

### ⭐⭐⭐⭐⭐ Make your 3D prints hold together better.
*by P***N on 3 October 2023*

easy to install in a 3D print, just make sure they go into the print correctly and you will have good results.

### ⭐⭐⭐⭐⭐ Well.. they’re heat inserts.
*by D***W on 24 December 2022*

Not too much to say on this one — simple product.The threads are smooth, machining quality is reasonable. They sink nicely into plastic once a soldering iron is applied, and hold firmly.. does the job excellently. I use these for mechanical parts made with a 3D printer.I’d buy another set if I ever need more.

### ⭐⭐⭐⭐⭐ Fit and stay in.
*by A***R on 4 January 2022*

Reviews of different types showed these with the slanted knurls hold best. Easy to insert into plastic part (with hot tip - I use a clean soldering iron). Seem to hold well even when only inserted into front of a part (where bolt will be pulling it forwards). These make a neat job, the threads should last (threaded plastic does not) and overall they have a smaller radius than a nut so can be used where space or accessability is limited.
