Review on 🔩 AJOYIB Brass Threaded Insert Nuts - 300Pcs M2 M3 M4 M5 Female Thread Knurled Nut Inserts for 3D Printing Project by Giles Lacoste

I got them for my 3D printer and they work fine. There's nothing special about them, but you shouldn't expect that at such a low price point. Buying a set of high-quality mcmaster thread inserts will cost you several hundred euros. If you take pride in what you do or are renovating, consider a more expensive option. Whether you're just renovating or doing cheap stuff, this will fit the bill.
