Scale Spoon The spoon is handled as a normal spoon. But for recipes, it is nice to know the weight of the ingredients. Apart from the loaded spoon with a flexible beam, a second beam is not loaded but carries a scale. When the spoon is filled, the beam will flex and the scale gives an indication of the weight. The scale has to be calibrated with known weight values. The OpenSCAD file is included to make variations easy to carry out.
