Car door lock pin

//The blue one on the picture//

I printed with:
0.12mm Layer Height
20% infill
200 °C Extruder Heat (optional to your material)
60 °C Bed Heat (optional to your printer)
NO SUPPORT
40% printing speed
I also changed the overall size in CURA printer to 102% (XYZ), so after cooling, it will be still the size I needed.

There is a M4 thread inside like in the base ones, that's the reason for the slower printing.
If you use these slow options and small layer height, you'll need no supports!
I designed this pin for my car a Seat Cordoba 2002.
