Review on 🔧 iplusmile Brass Knurled Nuts - Threaded Heat Set for 3D Printer & Projects (100pcs, M3 Thread, 3x4.6x5.7mm) by Keith Desjarlais

I used these to put inserts in some of the 3D printed plastic parts that hold my composter together. They've been in the Florida sun for weeks and the pieces still stick together like new. The bonus is that when I broke the plastic part I was able to pull it out again with a soldering iron and reuse it for a printed replacement. I will definitely buy more when I run out. So far I've dipped them in PLA and PETG, both printed at 50% infill with no problems.
