Plumb line is a tool used widely by carpenters to build straight edges. wikipedia: A plumb bob or a plummet is a weight, usually with a pointed tip on the bottom, that is suspended from a string and used as a vertical reference line, or plumb-line. It is essentially the vertical equivalent of a "water level". EDIT: The bob is now hollow and can be filled with sand or pebbles or any other heavy material to make it more stable.

Custom Section Project: Plumb Line Bob A plumb line has been used since ancient times, and it still remains an essential tool for building physical objects all over the world. The design of plumb bob has changed from a simple stone hanging on a string to a pointed, more accurate and stable design. This project aims on printing a quintessential tool for a maker and motivate children on learning more about hand tools used in building physical objects. HOW TO USE: Just push a piece of thread through the cap, and tie it to the bars on the inside of the cap. After this is done just push the cap through the hole on the top of the body and twist to lock it in place. Now this string is ready to be hung on any nail, or pin. The string once stable, will be a straight line perpendicular to the ground regardless of the regularity of surfaces. EDIT: The bob is hollow and can be filled with sand or pebbles or any other heavy material to make it more stable.
