The GIF of Operation can be found at http://imgur.com/gallery/Ct49X. The Marble Lock is a security device designed to protect private spaces such as bedrooms and bathrooms from unauthorized entry. It is not intended for use outdoors or in fire exit routes, and children should be kept away from the marbles used in its operation. This lock is suitable for most standard interior doors in North America. Important Notes: When printing the base plate, ensure that your print bed remains cool and that you do not over-extrude the first layer. The swivel joint will only function properly if printed correctly. Required Components: To assemble the Marble Lock, you will need: * One interior door knob with a square rod protruding from it * Twelve 6mm Airsoft pellets * One optional 45mm tension spring
