We live in a windy area which tends to pull off most pegs. These seem to hold on really well. They only use 2g of filament and take less than 10 minutes to print.
So far I have been printing with the following settings, but I haven't done any tweaking as they have just worked well.
0.28mm layer height
4 walls
15% infill
PLA
