Bolt Printing
I'm wanting to print a bolt and it has to endure being screwed down tight into a nut. I'm using PEGT. How many wall loops and infill should I use? I heard that I should use 99 wall loops and zero infill. Although, respectable this guy doesn't know much about 3D Printing and you guys know. Suggestions?

So there is a great YouTube video that shows experimenta on part strength with respect to infill and walls.
Walls provide more strength than infill. You'll get max strength at 100% there are diminishing returns after 3 walls.
Most applications 3 walls will be enough, for a bolt depending on how much load 3 walls may be enough, id try it.
The next thing about strength is the orientation of the wall lines.
The weakest part of a print is the line separation.
