    Materials and methods

    Print in one piece without support, Performance PLA can give about 60 degrees of motion but other filament or tuning the settings can give more or less.
    Inexpensive PLA will not work and will crack. Tested with Polymaker PolyLite and Hatchbox PLA-Pro and both work well.
