I have noticed that myself whilst browsing through some projects on thingiverse, in almost all cases I have ended up designing my own parts in openscad.
But I also noticed that the direction of your print always depends on which way you need the part to have the most strength, i.e. if you are going to print part of a "finger" it should be printed laying down so the strength of the layers will work in combination with each other, if you print it standing up, then that part will be weak if any pressure is applied to either end, it will just snap off at one of the layers.
and a quick dip in acetone bonds each layer together to form a much stronger bond.
I am not really sure on how much pressure/force you think these parts will be subjected to, if it is wear and tear you are worried about, adding rubber to the parts such as the finger tips, will reduce the amount of abrasion on them (use that rubber dip used for tool handles), for moving parts, I would reinforce each union with metal bearings, or bushings to reduce wear, if you are worried about longer/wider parts that are thin, these can be reinforced with steel or carbon fiber rods.
