FANTASTIC! I have printed several hands, various sizes to experiment. I can't seem to get any size to work with Chicago Screws. The screws seem way too big for the hand. I purchased all of the recommended sizes of the screws but they don't fit. I drilled some of them to be bigger but they either cracked the plastic or were so tight that the fingers did not bend. Am I the only one with issues related to the Chicago screws? Anyone find something better to use? I won't be using the hand for a real person - we are using in an engineering class focused on adaptive technologies and prosthetics.
