M4 connector stud

I was looking for ways to turn all my existing Raspberry Pi case with VESA mount into a Raspberry Pi cluster. While the goal can be easily achieved by sourcing M4 connector stud from hardware store, it would be interesting to see if a 3D printed one can do the job. And here it is! The model posted here is tested with M4 screws and nuts from hardware store for compatibility. 

Caution

This is clearly not the most economical way to get a connector stud. The material cost and print time needed would definitely make sourcing a connector stud from hardware store a way better alternatives. It is more a study on how far I can push my Prusa Mini on making mechanical parts with fine details that matter. 

Print Setting

Nozzle diameter: 0.4mm

Layer height: 0.05mm (this is essential to get those thread correctly printed)

Support: No

Brim: Yes

Infill: 100%

Material: PLA (Prusament strongly recommended as there is not much room for extrusion inaccuracy)
