305 Pcs Brass Knurled Threaded Insert, M2 M2.5 M3 Female Thread Brass 3D Printing Knurled Nuts, Thread Knurled Press-in Insert Nuts, Embedment Nuts for Plastic Shell 3D Printing Parts

These inserts work really well for my 3d prints and i haven't had a single issue with any of them at all they are extremely easy to use, strong and you get a TON for the amount that you pay for so i would highly recommend this to anyone who needs something like this.

This is good to keep in your toolbox for everything

You need to use an adapter on your soldering iron, place in the hole partially, now press into place with a hot soldering iron.I bought these to bolt together a riser for my 3D printer (K1 Max) once the riser is printed you pick one of these brass threaded insert.These are put into place with an adapter in the end of your soldering iron, once in place a bolt is screwed grom the outside into one of these.Need to use 8 of these when used to build the riser on a 3D printer.Pack contains several sizes, so you should fine the size you need.Very clever, useful itemWarning, dont heat them up too much or you will melt the 3D filament (plastic)

Used these to build 3D items that need to be disassembled, they work perfectly and the screw set I purchased to go with them fit without issue.

I have been using these for the last few weeks in different 3d models and they are good. Very handy to have different sizes in one box.

Work as intended no issues at all

Great product. Would be nice with possibilities to by larger quantities of specific sizes too

buen producto con todas las medidas que necesitaba, contento con la compra, seguro que volvere a comprar mas adelante, recomiendo al vendedor

Ottimo in tutti quei progetto con stampa 3D. Per un prossimo acquisto prenderò delle misure più grandi. Resta complicato trovare le viti adeguate, siamo a livello di modellismo, però il prodotto è valido per finalità specifiche.

If you're into 3D printing this one of the sets you'll definitely need. I use them almost on a daily basis and in many cases are a life saver Instead of screwing the bolts directly into the plastic, which will ruin it over time, I mount the hot inserts. Nice find

Satisfait du produit, que j'attendais beaucoup .
