Locking socket (1/2 and 3/8)

A socket holder for 1/2 inch and 3/8ths sockets. when a socket is placed on and is given a quarter clock-wise turn, the holder expands and locks the socket in place. Will hold a surprising amount of force. Prints in one piece. Before trying to free the moving parts insert a m3 bolt into the underside as it can help avoid breaking the print. based off of a 0.15mm tolerance between moving parts so make sure your printer is dialled in.
