The Stupefying Lock

This is our 3D printed stall lock designed for school kids of all ages. This is made by the girl scout troop 149058. If your school bathroom stall locks are broken, you could give this a try. It's designed to fit all door sizes. All you do is you put it at the bottom of your stall to close the gap between the door and the other side, and screw the screws in tight. Then, the door will be locked, and you can have your privacy.
