• Resumen

  • In this paper we explain how to build a very sensitive force table using 3D-printed parts. The key component of this apparatus is a simple sensitive pulley that, together with the other components, can be printed in one day (one hour per pulley, 17 hours for a complete three-pulleys table) at the cost of 160 g of plastic filament. This force table can be used in a vertical position on a whiteboard for an all-class discussion or in a horizontal position for personal or group usage. The design includes calibrated mass hangers that use coins or small metal pellets as weights.
