ruthex M3 Threaded Inserts VORON - 100 Pieces RX-M3x5x4 Brass Heat Set Insert for Plastic Parts - Metric knurled Nuts - Insert by Heat into 3D Printing Components

I used these in some 3d prints and they worked great and held together. Their sizing is also accurate, as I double checked with some digital calipers. I was really bored and even counted how many came in the bag. The bag said 100, and I counted exactly 100. Not bad.

I am working on an EVA3 tool head for a Zero G Mercury 1.1 conversion and got these since they were the correct size from the bill of materials. They came neatly packaged in a bag and work as expected. They were easy to install with a heated soldering iron to push them in. The grip seems strong and the M3 screws thread perfectly through the inserts. Extremely happy with these and looking forward to using them to secure more prints and help me finish my conversion!

Sizing was spot on for Sherpa heavy build. Easy to use and strong hold.

They do the job

I usually keep a bunch of these on hand to add M3 threading to heavier duty 3D prints. They're consistently machined within very good tolerances, and there haven't been any surprises. Work well with PLA, PETG, and ASA plastics that I've used.

I've used other heated inserts with the threads on opposite sides of the tubes but these are much better! These are thinner on the end you insert so that they run along the printed hole with opposing heat threads at the "Top" of the insert. Other inserts have to melt the plastic at the insert entry point which can gum up the threads and require cleanup first. These also tend to go in much straighter as the thin portion acts as a guide, with the melt mostly occurring at the top. I can't speak to strength differences as in my designs, the force is pulling from the other end but they are quicker and straighter to use!

Work great, used them in a bunch of 3D printed items

I've been using these for a while in my 3D printing projects for functional parts. They work great, look great, and are very easy to use with the Ruthex soldering iron insert tips. Definitely a must have for anyone printing functional parts or printer modifications.
