This model needs to be printed at 0.1mm layer height (any typical nozzle diameter should be fine) and should be printed with a 60 degree infill direction, and a 120 degree bridge direction. This gives your hinges the best shot at being strong during repeated folding. Also, this model needs to be printed flat side down! You should not need any supports for this one.
