It completely depends on the filament, infill, nozzle size, and layer height. For a small PC case personally I think 3mm is enough. But bear in mind the stress point (hole for screw) is very close to the corner. This will be the weakest link by far.Stuck in the office right now It's mainly because the screws aren't screwed in. But also the surface that had support underneath isn't totally flat.EDIT - By the way, given 3mm screw diameter, I measured the max length to be 7.5mm with the original design.
