Exercise in making compliant torsion springs, this one has a rotational range of approximately 120 degrees (Has not been precisely measured) and the lever arm can generate a satisfying thwack when it slams into other objects while retracting
Central hole is a ¼" square, and fits standard socket drivers in that size
License is public domain, feel free to use it as inspiration or integrate it into some larger contraption, Freecad design file is included for reference
Has been tested in Polymaker Polylite PLA Pro, but most polymers work for this, standard PLA may be too brittle however
