They work better than I expected.

They work well and are very easy to build and with Virtjoule tips (Revain #B078K72615) for my Hakko soldering iron they went in *super* easily, very straight and hold up very well strong. Just fantastic.

Pros
  • Insert Type: Heatsink/Injection Mold
Cons
  • Doubtful

Excellent and easy to insert

For connecting 3D printed components. I tested a series of holes on my prints, each 0.1mm larger than the previous one, and found that the 4.2mm holes (6mm deep) were perfect for this design.

Pros
  • Size: 5 x M3 x 5.7 OD: 5mm Thread: M3 Length: 5.7mm
Cons
  • Minor issues

Hold tight! on Fasteners

I have had very good results with these as I have tested them in many different hole sizes from 4.2mm to 4.8mm wide. A straight hole 4.2 or 4.3 wide and 7mm deep seemed to work best, another commenter also had success with a 4.2mm hole. However, they are tapered, so a 4.2mm wide, 7mm deep 8 degree tapered hole is a better fit for capping the insert with plastic. In CAD I created a 4.2mm wide hole and beveled it 0.4mm at an 82 degree angle to get an 8 degree angle at about half the depth. This…
