Beranger type weiching scale model

This is a working model of Beranger type scale. This model is fully usable, and gives 0.5—1 gram accuracy right from the printer without additional hardware — due to ingenious mechanics, invented in the late XIX century. There is no rotating pivots involved!

Please, note — this is fully working, but mostly demonstrative model, so it may not serve well as an everyday tool. I've "stretched" the mechanism vertically and made it narrower for better observing and greatly simplified stopper mechanism.
