Indispensable if you're into 3d printing. You can never have too many.

Used for many 3D prints. Seems to work well and a good price

Works great in PLA. I use an OD of 4.2mm for my hole and a temperature of 250C to insert them and they work fine. No issues with burred threads or galling.

I use so many of these. The quality is amazing. Zero issues with any of them. Open your world of 3d printing up to the possibilities of actually screwing pieces together that hold.

What more can I say? Size and threads were correct and they haven't come out of anything yet!

I always keep some of these around for 3D printing projects; 3d printed threads never work very well, so I like to use the metal insert instead.These work just as well as any others I've had; I typically heat the insert with a soldering iron push them into the pilot hole in the print. I've used about 10 of them so far, and all the threads were cut well and smooth. Would highly recommend.

I bought these to use on an RC jet boat project. The only thing is that some of them pulled out but it's possible there wasn't enough plastic around the holes to hold these effectively.
