Kadrick 200Pcs M2 Threaded Inserts for 3D Printing Components,M2*3 * 3 Metric Brass Knurled Nuts, Insert by Heat into Plastic Parts

No more jank in my 3d prints. These leave such a high quality connection point for my 3d prints

The media could not be loaded. Works just as expected and no issues with setting them using a soldering iron. Case is sturdy enough but I'd keep a rubber band around it just incase, would hate to have it accidentally open and try to pick up all the inserts. Only have tried the m5x10 and it worked perfect with my m5 bolt that I used. Great value for the money and good variety to test out. Will refill with the same brand as needed.

Great quality and they work like they should.

Used for my 3d prints. Works great.Holds tight into my prints. Assortments are nice as random projects come up all the time. Love it!

These are good inserts for the price. They don’t spin when a torque is applied to them, and they are easy to install correctly. Just use the hole size listed for the smaller diameter and it fits like a glove. Also, make sure you use enough perimeters around the hole to ensure it’s good strength. I usually do a minimum of 4 perimeters around the holes.

Almost too much variety. Nice set with a lot of size options

Perfect screw set for use with 3D printing projects

I make a lot of functional parts with 3D resin printing. And even when buying the 'tough' resin, it still won't hold threads well, so these threaded inserts are a life saver. I make the holes about 2% bigger than the actual size, to accommodate any shrinkage during resin curing. Then when it's all done, I get a drop of medium thickness ethyl cyanoacrylate glue, use a toothpick to spread it all around the sides and insert it into the hole (it helps to keep the bottom of the hole open all the way through with just a tiny ridge to stop the insert at the right depth). Once dry, this insert is nearly as strong as when heat-set into standard extruder type 3D prints (if not as strong). Now I can add screws to covers for my prints making them more even more functional and professional looking. Inserts are very accurate in their machining, and all have proven to be exactly the same, with no massive e variations in their size or fit. Highly recommended.
