Had very good success with these as I tested them in many different size holes from 4.2mm to 4.8mm in width. A 4.2 or 4.3 straight width hole 7mm deep seemed to work the best, another commenter also had success with 4.2mm. However, they are tapered so an 8 degree tapered 4.2mm wide and 7mm deep hole worked better to get plastic coverage all around the insert. In CAD, I created a 4.2mm wide hole and chamfered it at 0.4mm 82 degrees to get an 8 degree angle about half way deep. This allows nice coverage around the insert with very minimal blowout. It can be harder to insert these straight, by hand, if you use straight holes. I've found straight inserts insert straighter using straight holes and tapered inserts with tapered holes. Although, it might not matter as much for most if using these for 3d printed parts.

I love these lil guys. I just wish they weren't so expensive or could get more for the money. Use them on lots of my 3d projects

These work well and are very easy to design with, and using the Virtjoule tips (Amazon #B078K72615) for my Hakko soldering iron, they went in *super* easy, very straight, and hold very strong. Just fantastic.

These have the knurling that is made to HOLD. The super cheap ones have vertical knurling that does NOTHING.

They do exactly as they should, work good embedded into PLA, PETG, PC-CF, PEEK.

Used for making connections between 3D printed components. I tested a series of hole features in my prints with each hole 0.1mm larger than the previous, and I found that 4.2mm holes (6mm deep) worked perfectly with this design.
